    Abstract We present a method to enhance the layered structure of surface-stabilized ferroelectric liquid crystals (SSFLCs) for low-voltage, high-speed operation in electronic holographic displays. By applying a combination of heating, slow cooling, and square-wave low-voltage (<1 V), we reduced the switching voltage and achieved sub-1 ms switching times, fulfilling the 360–720 Hz requirements for spatial light modulators (SLMs) in electronic holographic displays. The proposed method also suppressed zigzag defects, improving uniformity and light efficiency. This work advances high-resolution SSFLC-based SLMs for next-generation 3D holographic displays.

    Abstract In this work, heteroepitaxial growth of copper phthalocyanine (CuPc) on a large single-grain of thin film N,N’-Di-n-octyl-3,4,9,10-perylenetetracarboxylic diimide (PTCDI-C8) was investigated. Vacuum-deposited PTCDI-C8 thin films at a growth temperature of ∼180 °C exhibited large grain growth of several hundred micrometers or more in size, and their surface consisted of stripe islands with molecular steps. CuPc deposited at 180 °C on this PTCDI-C8 large grain underlayer was found to grow epitaxially with its needle-like crystals dominantly oriented in one unique direction. The mechanism of the observed epitaxy is discussed based on the results of in-plane X-ray diffraction and the initial growth morphology.

    Abstract We clarified that a ferroelectric liquid crystal (FLC) has high resolution display capability as small as 1 × 1 μm pixel pitch using an FLC pixel array with a two‐layer electrode, which has a 1 × 1‐μm‐checkered apertured electrode and a plane electrode separated by an insulation layer. By applying +2 V to the apertured electrode and −10 V to the plane electrode in the two‐layer electrode and 0 V to the transparent common electrode, a checkered pattern was clearly observed, which indicates the successful individual pixel driving with a pixel pitch of 1 × 1 μm. When fabricating 1 × 2‐μm‐pitch rectangular FLC pixels, we elucidated that the liquid crystal alignment direction should be along the shorter side of the pixels to avoid asymmetric transmittance distribution in each pixel. Moreover, we successfully reconstructed a 3D holographic image using 10 × 10 k FLC pixel array with a pitch of 1 × 1 μm driven by the two‐layer electrode with hologram‐patterned apertures. We showed that FLC is a strong candidate material for realizing spatial light modulator with extremely small pixel pitches, which is essential for holographic displays with wide‐viewing‐zone angles.

    For directional control of organic single crystals, we propose a crystal growth method using liquid crystal as the solvent. In this study, we examined the formation of 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C<inf>8</inf>-BTBT) single crystals using a parallel aligned liquid crystal (LC) cell and rubbing-treated polyimide films in order to clarify the effects of LC alignment on anisotropic C<inf>8</inf>-BTBT crystal growth. Based on the results, we found that the crystal growth direction of C<inf>8</inf>-BTBT single crystals was related to the direction of the aligned LC molecules because of rubbing treatment. Moreover, by optical evaluation, we found that the C<inf>8</inf>-BTBT single crystals have a aligned molecular structure.

    To realize active-matrix flexible liquid crystal displays (LCDs), high heat resistance and high dimensional stability are required for plastic substrates. We have developed the fabrication process of flexible LCDs based on the coat-debond formation method using ultrathin polyimide (PI) substrates. In this paper, we fabricated post spacers on the PI substrates by photolithography and investigated the influence of spacer pitch on the image quality of flexible LCDs. As a result, we clarified that we can suppress the degradation of image quality of flexible LCDs in both non-curved and curved states by using narrow pitch post spacers.

    It is necessary to develop a flexible organic transistor with high mobility to realize a flexible display with high image quality. Thus far, we have clarified that it is possible to control the crystalline orientation of the organic semiconductor by growing soluble high-mobility organic semiconductor single crystals in the aligned liquid crystal solvents. In this study, we considered the single crystal molecular arrangement by evaluating the refractive index anisotropy for visible light and the absorption anisotropy for polarized ultraviolet light in the single crystal films formed by the liquid crystal solvent method.

    For realizing substrate-free liquid crystal displays with high contrast property, we have been forming alignment-controlled liquid crystal droplets in molecular-aligned polymer. The composite films are obtained by phase separation induced by ultraviolet pattern exposure when the alinement of the liquid crystal and monomer solution is controlled by rubbed alinement layers on two substrates. In this study, we clarified that the morphological formation of liquid crystal droplets can be controlled by photo masks and aggregation conditions including temperature and ultraviolet light intensity.

    To achieve electric holographic displays with wide field of view, it is necessary to fabricate the display device with sub-micron pixel pitch. We have proposed new pixel structures having dielectric walls to reduce the fringe electric field leaking to the adjacent pixels. In this paper, we discussed a relationship between quality of reconstruction images and width of the dielectric wall. We clarified that the quality of reconstruction images is adequate when the width of wall is 250 nm or less. In addition, we also investigated the LC alignment on the surface of dielectric walls. As the result, it is recognized that the LC molecules align parallel to the wall surface and degrade the uniformity of LC alignment. From the above, we obtained the policy of designing wall structures and materials.

    Recently, realization of flexible displays has long been anticipated as a next generation display technology. To achieve the high quality flexible displays with wide viewing angle range, we have proposed the blue phase mode liquid crystal (LC) devices having polymer walls inside of the LC cell to stabilize the cell gap during bending. In this report, we investigated the effect of monomer concentration on the electro-optical properties of flexible blue phase mode LC devices. As a result, we clarified that we can suppress the residual retardation and reduce the driving voltage of blue phase mode LC devices by optimizing the concentration of monomer materials.

    We have developed a transfer technology to fabricate a flexible organic TFT (OTFT) backplane for a large-area and high-resolution flexible display. The OTFT backplane, which was formed on a glass substrate with a temporary adhesive layer, was composed of gate electrodes, polymer gate dielectrics, source/drain electrodes, an organic semiconductor layer and pixel electrodes. After formation of passivation layer and bonding of a plastic film on the surface of the backplane, it was peeled off the glass substrate. The electrical characteristics of the OTFT backplane were evaluated, before and after the backplane was transferred. We have confirmed that a transfer technology is effective in fabricating flexible displays.

    We studied the spectral dependency of flexible OLEDs on thickness of barrier layers which protect from moisture or oxygen. While the spectral shift depending on the viewing angle were observed in OLEDs with SiO_2(50nm)/SiN_x(70nm)/SiO_2(100nm) barrier layers, we found that the spectral shift of OLEDs with SiO_2(50nm)/SiN_x(40nm)/SiO_2(35nm) barrier layers could be suppressed for the viewing angle change.

    In flexible liquid crystal (LC) displays, the electrooptic properties of the LC layer is changed and display image is disordered when the substrate gap is changed by substrate deformation and spacer damage. In this study we have proposed a formation method of robust line spacers on a plastic substrate based on roller nanoimprint technique using a nickel mold plate. We fabricated a vertical-alignment LC device using two different plastic substrates with the striped spacers and comb-like electrodes. We confirmed the light modulation of the flexible LC device.

    We proposed a new flexible liquid crystal (LC) device, in which twisted nematic LC layer is stabilized by molecular-aligned polymers. The polymer walls and networks, which were formed by photo-polymerization-induced phase separation, suspended two plastic substrates, and the polymer networks also stabilized twist LC alignment. The polymer walls and networks increased the threshold voltage for LC alignment change. However, the polymer networks fastened the decay response time because of reduction of LC back flow phenomenon.

    Flexible thin light-weight displays are recently expected as next-generation technology for creating various electronic display styles in ubiquitous and universal information services. To realize a flexible display for high-quality moving images, we have been developing plastic-substrate-based organic light emitting diodes (OLEDs), liquid crystal (LC) devices, organic thin film transistors (OTFTs), and their low-temperature fabrication process. In flexible OLED, phosphorescent polymers with high efficiency were used in light emitting layer. In case of LC devices, fine polymer structures were formed in a fast-response LC layer to keep substrate gap constant. We also fabricated low-voltage OTFT array on a plastic substrate for driving the OLED and LC devices.

    The three-dimensional alignment technique for liquid crystal devices is presented that consists of polymer walls made from UV-curable monomers that are oriented by an electric field while cured with a spatially patterned UV light source. From the observations of polymer wall by using polarizing Raman scattering microscopy, it was found that the polymer alignment depended on rubbing direction on two-substrates and applied electric field in photo-polymerization. This technique provides defined boundary conditions of the liquid director field in three dimensions.

    We have developed an A4-sized ferroelectric liquid crystal (FLC) displays using a flexible backlight sheet. The flexibility of backlight was obtained by combination of side light of three-primary-color LED chips and a flexible-polymer thin light guide plate. A plastic substrate with low thermal distortion was adopted and a compounding ratio of liquid crystal and monomer was adjusted to improve the molecular alignment of a composite film of the FLC and fine polymer fibers near polymer walls. Color moving images were displayed on a flexible screen by driving with an active matrix technique using external switch transistor array based on a field-sequential-color method.

    We studied cholestric liquid crystal alignment induced by stretched polymer filaments. The fine polymer filament was fabricated by extending and exfoliating nonwoven cellulose cloth. The filament was sandwiched between glass substrates, and cholesteric liquid crystal was filled in the substrate gap. The polymer surface anchors liquid crystal directors to the filament direction. It was observed that helical axis of cholesteric liquid crystal near the filament was fixed to be perpendicular to the filament direction. The local control of helical alignment using stretched filaments is applicable to electronic paper and photonic band crystal applications.

    We so far clarified that organic semiconductor pentacene is soluble in heated liquid crystal (LC) and single crystals of pentacene are growing in a solution cell in cooling process. In this report, we evaluated optical properties of perntacene/LC solution and controlled solution conditions to consider the segregation mechanism of pentacene single crystals. For this experiment, we dispersed small particles to change surface energy and LC alignment in the solution cell. As a result, the number of pentacene crystal nucleus segregated in the cell increased remarkably.

    In this study, we have investigated the effect of surface treatment on the morphology and mobility of pentacene by using a photoreactive polyimide film to modify the gate-insulator surfaces of organic thin-film transistors (OTFTs). Surface modification includes a photoreactive polyimide film, presenting a passivated interface on which the pentacene film can grow. This polyimide film can control of the grain size of pentacene by using linearly polarized deep UV (LPDUV) irradiation. Fabricated OTFTs include stacked structures of Ta2O5 as the gate insulators and the photoreactive polyimide. Most of the characteristic parameters of the OTFTs, such as carrier mobility and on/off current ration, have been improved by using the photo-alignment treatment achieved with LPDUV irradiation.

    A bottom-contact organic TFT (OTFT)-driven 16×16 polymer-dispersed liquid crystal (PDLC) display panel on a flexible plastic film has been developed. The OTFT showed a carrier mobility of 0.3cm^2/Vs, a current on/off ratio of over 10^5, and a low operating drain voltage of -6V. We also successively confirmed display operation of the fabricated 16×16 display panel.

    We have studied the molecular alignment of polymer-walls through polarized Raman spectral microscopy. These walls were founed in liquid crystal by local photopolymerization-induced phase separation under an electric field. We found that without any applied voltage the side-chain molecules of the polymer-walls oriented in the rubbing direction of alignment layers coated on the substrate, but with applied voltage the molecules oriented along the electric field. Novel three-dimensional alignment technology realized by using the interfaces of both the polymer-walls and alignment layers could stabilize the bend configuration in the π-cell.

    Various multiplexing methods have been studied in holographic recording. Phase-code multiplexing method is promising because there is no mechanical movement and there is possibility of fast access. Several papers described multiplexing characteristics using Walsh-Hadamard transformation. In this paper, we focus on phase-code multiplexing characteristics using discrete cosine transformation.

    We studied liquid crystal alignment induced by micropolymer filaments. The polymer filaments are extracted from a nonwoven cloth by extending and exfoliating it. The formed filaments were sandwiched between glass substrates, and then the nematic liquid crystal was filled in the gap between the substrates. The liquid crystal director orients along the filaments. The two-dimensional arrangement of filaments enables spatial alignment control of liquid crystal in a device plane.

    We developed a fabrication process of a large-size flexible display device containing monostable ferroelectric liquid crystal(FLC) with aligned polymer walls and networks. Finely patterned color filters and ITO electrodes were formed on a plastic substrate by transfer method. An FLC/monomer solution film was then coated on the plastic substrate by flexographic printing technique. After lamination with another substrate was performed, the polymer structures were formed by the FLC by two-step UV irradiation. A fabricated A4-sized device with color pixels presented images even when the device was bent.

    Light diffraction of aligned polymer fibers was investigated, which were formed by a phase separation of a liquid crystal and polymer mixture in an anisotropic phase. It was confirmed that the light diffraction pattern of He-Ne laser beam due to the polymer fibers depended on anisotropy and periodicity of the dispersed polymer fibers. The angles of the first order diffraction peak were corresponding to values calculated with the periodidty of the formed polymer fibers. This method using the light diffraction is useful for quantitative evaluation of the polymer fibers.

    This paper describes a new-structure lurninaire system with a xenon discharge lamp and a liquid crystal filter, that controls color temperature of illuminating light widely and continuously according to the voltage applied to the filter. We designed and fabricated a new optical filter by laminating two different types of liquid crystal devices, that individually decrease and increase color temperature of transmitted light by varying the spectral balance of incident light from the discharge lamp. Each liquid crystal device contains different dichroic dyes and absorbs short-or long-wavelength visible light. The degree of absorption can be varied by controlling the applied voltage. From the fundamental optical experiments, in which a high-pressure xenon discharge lamp of neutral color temperature of 5600K with almost flat radiation spectrum was combined with the liquid crystal filter mentioned above, we found that the color temperature of light radiated from the system can be varied from 3800K to 8200K. The presented luminaire system is especially useful for capturing video and photographic images and for appreciating art works when strict color temperature control is essential.

    We studied the influence of polymer molecular weight on the phase separation of a liquid crystal (LC) and a polymer. The critical temperature of the phase separation was increased according to the increase of the polymer molecular weight. The obtained critical temperatures were compared with the theoretical values calculated for Flory-Huggins free energy. As a result, it was clarified that parameter D, which means the molecular interaction between the LC and the polymer in Flory-Huggins interaction parameter_χ, increased with the increase of the polymer molecular weight. This result indicates that the large interaction between the LC and the polymer decreases, as the polymer molecular weight increases and the interaction is finally saturated. The change of the molecular interaction was also obtained by measuring the mixing enthalpy using differential scanning calorimeter.

    We fabricated flexible reflective devices consisting of monostabilized ferroelectric liquid crystal (FLC) with polymer walls and networks. To control the thickness of the thin composite film, etched spacers were formed on a plastic film substrate by photolithography. An FLC/monomer solution was uniformly formed on the substrate by flexographic printing method to obtain spatial uniformity of the thickness of the composite film. An insulator layer was also formed on the other substrate to avoid short circuit between ITO electrodes. After lamination was performed, the polymer walls and networks were formed by two-step irradiation of ultraviolet light. A fabricated reflective FLC device exhibited mechanical flexibility and light modulation with grayscale capability.

    We studied bending-iteration tolerance of a flexible ferroelectric liquid crystal (FLC) device containing polymer fiber networks and lattice-shaped walls for future roll-up screen displays. We first confirmed stability of smectic layer structures in a monostable FLC device without polymers when shearing glass substrates. We then fabricated a flexible monostable FLC device (size : 10cm xlOcm) with plastic substrates by utilizing two-step photopolymerization-induced phase separation processes of FLC/monomer solution. We repeated bending the device at a minimum curvature radius of 20mm in time period of 20s. As a result, the microscopic texture and electrooptic effect of the FLC stabilized by the polymers were not changed even after bending of over 1000 times.

    We fabricated a new guest-host liquid crystal (LC) device using extended porous polymer films. We filled the nematic LC material containing black dichroic dye (concentration; 3wt%) in two laminated porous polymer films (thickness: 7 μm, porosity: 45%), which were extended in advance, and the composite film was then sandwiched by glass substrates with transparent electrodes (no alignment film). As the LC molecules align in parallel to the extending directions of the polymer films, the two LC alignment directions in the polymer films are orthogonal. As a result of measuring the light modulation characteristics with white incidence light, we recognized that the device can modulate the no polarized incidence light.

    We have evaluated the polar anchoring strength of a thin molecule-aligned polymer film formed by a liquid crystalline monomer. The polymer film was obtained by photopolymerization of the monomer oriented by a rubbed polyimide alignment layer in a chamber filled with N_2 gas. We fabricated a nematic liquid crystal cell using the thin aligned-polymer films as alignment layers, and then evaluated the polar anchoring strength of the polymer by measuring optical retardation curve of the cell driven by voltages. As the experimental result, the anchoring strength was one order of magnitude less than that of a conventional rubbed polyimide alignment layer. Besides the anchoring strength decreased with increasing a cure temperature of the monomer film. It is thought that this is because the alignment order of the polymer decreased with increasing the cure temperature. It was found that the anchoring strength of the molecule-aligned polymer surface can be controlled by the alignment order of the polymer.

    In this work, we investigate the stabilization of bend alignment and its mechanism in pi-cell consisting of polymer-walls formed by local photo-polymerization under electric field using liquid crystal/polymer composites. This fabricated-cell can be stabilized into the bend configuration and has no need for the initialization voltage to induce the splay-to-bend transition. We observed the configuration of the changes in the liquid crystal molecules during the splay-to-bend transition for pi-cells with polymer-wall structures, which were arranged in a square grid by controlling parameters, such as a geometric construction between rubbing and wall directions, a pre-tilt angle on substrates, and an orientation of polymer-wall. As the result, we found that the free energy based on three-dimensional alignment formed in both interfaces of the polymer walls and substrates greatly worked for the stabilization condition.

    We propose a novel bend-alignment liquid-crystal (LC) cell with a three-dimensional aligned polymer, which can stabilize the bend state in the initial stage. This bend-cell was fabricated by using photo-polymerization-induced phase separation under an electric field. As the mixed solution of the liquid-crystalline monomer and LC sandwiched between the two substrates was subjected to an electric field and partially irradiated with ultraviolet light, the monomer aligned with LC molecules was polymerized to form a vertical wall with respect to the substrate. Consequently, the bend-alignment of the LC was stabilized by both interfaces of the polymer wall and substrate. The fabricated device exhibits great potential for display applications, such as no need of the initialized voltage to transit form spray to bend state, and no operating bias voltage above the critical voltage to keep the bend-state.

    We studied the flare appearing in video images when a liquid crystal filter is used in front of a video camera. To clarify the generating mechanism of the flare, the relationship between the concentration of spacer particles dispersed in the liquid crystal and the intensity of light scattered by the filer was examined in detail by using a schlieren optical system with a laser light beam. We found that the light scattering is mainly caused by the spacers and glass substrates, so we evaluated their contribution ratio. From microscopic observation, we determined that the light scattering originated by the spacers includes light scattered by the spacer particles and that resulting from by liquid crystal alignment deformation caused by the spacer surfaces. As the light scattering of the spacers was in proportion to the spacer concentration, it could be considerably reduced by decreasing the spacer density. The flare in video images was reduced by decreasing the light scattering. The liquid crystal filter fabricated by using the flare-reduction method described above was utilized in actual television program.

    A new type of electrically controlled optical filter to heighten the color temperature of incident light has been developed that is comprised of guest-host mode liquid-crystal devices containing dichroic dyes. The transmission spectrum of the filter was designed as the ratio of different radiation spectra based on the black body radiation theory. The absorption for long-wavelength visible light is varied according to the liquid crystal alignment change for voltage applied to the filter. When white light with a color temperature of 5700K was incident on a filter fabricated with 6&mu;m-thick liquid-crystal layers, the color temperature of light transmitted from the filter could continuously be changed from 6000K to 11000K by voltage control of less than 10 Vrms. The electrooptic response time was as fast as 50 ms. This liquid crystal optical filter is widely applicable to color-image input/output technologies, including the image sensing, display, and illumination fields.

    We have developed a fabrication method with printing for light-weight, large ferroelectric liquid-crystal (FLC) devices with plastic film substrates. The proposed method uses flexographic printing. An FLC/monomer solution coated on an anilox roll is deposited on a letter press and then transferred from the press to the surface of the substrate. The pressure of the roller used to laminate the solution between two substrates was adjusted so that the upper substrate was pressed onto spacer particles dispersed in the solution film. The formation of air bubbles in the film was considerably reduced by heating the substrates to 50t. A laminated solution film was pressed beneath a glass sheet to prevent curling of the substrates and to make the film temperature uniform. The solution film was then irradiated with ultraviolet light, causing polymer networks supporting the two substrates to form in the FLC. A device fabricated between polarizers exhibited a high contrast ratio more than 100 : 1 and grayscale capability.

    We studied smectic layer structures of ferroelectric liquid crystal (FLC) formed in elongated small spaces surrounded by molecule-aligned polymer walls and rubbed polyimide alignment layers. The polymer walls, which are parallel to a rubbing direction and upright to the alignment layers, were formed by photopolymerization of aligned monomer under patterned ultraviolet-light irradiation. We observed the alignment textures of the FLC between the polymer walls with a polarizing microscope. As a result, as the interval between the polymer walls decreased, it was found that the smectic layer structure was changed from vertical-plane bending alignment (chevron structure) observed with a conventional surface-stabilized FLC into horizontal-plane bending. It is thought that the smectic layer structure deformation is decided by the competition of the anchoring effects of the alignment polyimide layers and the molecule-aligned polymer walls.

    We studied the influence of cure temperature on polymer molecular weight in photopolymerization-induced phase separation of liquid crystal and polymer fibers, using gel permeation chromatography. As the experimental result, it was for the first time found that the molecular weight of the polymer, which is segregated and aggregated in a solution of monomer and the liquid crystal, increases with decrease of the temperature. We considered that the spatial concentration of growing polymer density, which is induced by the phase separation with temperature decrease, accelerates chemical bonding of polymer molecules.

    We have proposed and fabricated a thin ferroelectric liquid crystal device with large cone angle (45°), and studied its molecular switching behaviors. In the device, the molecular alignment direction is stabilized in rubbing direction of two polyimide alignment layers coated on substrates, by enhancing the influence of the anchoring effect of the alignment layers, where the rubbing strength is heightened and the liquid crystal thickness (1 μm) is small. The molecular alignment change from the rubbing direction occurs according to applied voltage, resulting in producing a V-shape electrooptic effect with continuous light modulation. As the alignment defects could be reduced by decreasing liquid crystal thickness, the device obtained a high contrast ratio of 250. We also considered a model of molecular alignment structure through measurement and simulation results of viewing-angle properties of the device.

    We improved flexibility of a polymer-stabilized ferroelectric liquid crystal (FLC) device by applying thinner substrates and optimizing the conditions for forming polymer walls. When the bending tolerance of the device (size : 1×6cm) fabricated using 100μm-thick plastic film substrates was measured, it could be bent in a radius of 0.7cm with keeping uniform FLC alignment. The deformation of FLC smectic layers was estimated to be extremely small from calculation for length change of the two substrates in a bent device. We also demonstrated that a larger device (size : 10×10cm) bent in radius under 2cm exhibited good display operation.

    We propose a novel bend-alignment liquid crystal cell with polymer walls structure, which can stabilize bend-state. The polymer-walls-stabilized bend cell was fabricated by the photo-polymerization-induced phase separation and electric field with molecular alignment. As the mixed solution of the liquid crystalline monomer and LC sandwiched between two substrates was applied electric field and irradiated with ultraviolet light through a photomask, the monomer aligned with LC molecules was polymerized. As a result, aligned polymer walls depending on the mask pattern stabilize the bend-alignment of LC. This fabrication process can separate the liquid crystal and aligned polymer regions. The fabricated device exhibits great potential for display applications, such as no need of the initialized voltage to transit from splay-state to bend-state, and no operating bias voltage above the threshold to keep the bend-state. In this paper, we discuss the fabrication process and features of the polymer-walls-stabilized bend cell.

    We studied a new method controlling spatially liquid crystal alignment using a molecule-aligned porous polymer film. The polymer film (thickness : 6μm, porosity : 92%) was formed by stretching a porous polymer film extremely. The polymer extended in one direction was sandwiched by transparent electrodes of glass substrates without conventional alignment layers after nematic liquid crystal was filled in the porous polymer. From the optical anisotropy of composite film of polymer and liquid crystal, it was confirmed that the liquid crystal molecules are aligned in parallel to the extending direction, and the fabricated device had a light modulation function based on the electrically controlled birefringence effect. Although the light modulation is obtained by using applied voltage of 10V, and it needs high saturation voltage of more than 50V for alignment change. This means that the molecular-aligned polymer surface exhibits a large anchoring effect for liquid crystal alignment. The rise and decay response times of the device were 3ms and 13ms, respectively.

    In current video productions using the virtual studio, there is no effective way to show the actors the positioning of virtual objects, such as CG characters. We have created and developed a new interface-Invisible Light, a special light which is visible to human sight but invisible to the television camera. In this report, we will discuss the effective use of Invisible Light within the Virtual Studio.

    We have studied flare effects induced in liquid crystal filters for video image capturing. The relationship between the concentration of spacer particles dispersed in the liquid crystal device and the intensity of light scattered by the device was examined in detail using a Schlieren optical system. The scattered light intensity was decreased with proportion to the spacer concentration. It was also found that the alignment disorder of liquid crystal molecules around the spacers causes considerable light scattering. The flare effect appeared in video images was reduced according to the decrease of light scattering.

    A composite film of liquid crystal and polymer networks is useful for supporting plastic substrates of a flexible display device. In this study, we studied the molecular alignment of polymer fiber networks, which are formed in ferroelectric liquid crystal by means of photopolymerization-induced phase separation, by Raman spectral microscopy using incident polarized infrared light. From the dependence of Raman scattering on the incident polarization direction, it was found that side-chain molecular skeletons of the polymer remarkably orient in the rubbing direction of alignment layers coated on the substrates. The polymer forming process was considered due to the molecular alignment evaluation.

    We have developed a flexible ferroelectric liquid crystal(FLC) device containing polymer walls and networks. The polymer walls are formed to support plastic film substrates and enhance mechanical stability of the device, To prepare the flexible FLC with polymer walls, the liquid crystal and monomer solution sandwiched. between two substrates are heated to be in isotropic phase and irradiated with ultraviolet(UV) light through photomask to form polymer walls without birefringence. After that, polymer networks are formed in the area surrounded by polymer walls by irradiating the solution with spatially uniform UV light. The fabricated device between crossed polarizers exhibited gayscale display operation even when the device was bent.

    We have developed a printing fabrication process for large and light-weight liquid crystal devices and have fabricated ferroelectric liquid crystal(FLC)devices with plastic film substrates. The proposed process is based on a flexographic printing method. FLC/monomer solution coated on an anilox roll was uniformly deposited on the letter press and then transferred to the surface of the substrate from the letter press. This method is able to control thickness and printing area of the solution on the substrate. Pressure of a roller for lamination was adjusted so that an upper substrate was pressed onto spacers dispersed in the solution. Formation of air bubble in the solution was reduced by heating upper and lower substrates to 50℃. And then the laminated cell was pressed by a glass to prevent curling of the substrates and to obtain uniform cell temperature. After the cell was irradiated by ultraviolet light, polymer network which supports the substrates was formed in the FLC. Alignment of liquid crystal modecules was observed. Light modulation effects including grayscale capability were also observed when voltage was applied between electrodes of the devices.

    A free-standing composite film of ferroelectric liquid crystal(FLC)and aligned polymer fiber networks supporting plastic thin substrates is expected to be applied to a large and light-weight sheet display in future. We clarified the FLC alignment structures formed between the fine polymer fibers, by polarizing microscopic study and X-ray diffraction measurements. It was found that bending of smectic layers of FLC is induced in both the film and cross-sectional planes at the phase transition from smectic A to smectic C of FLC. The light transmittance properties of the composite film between crossed polarizers was analyzed by light propagation simulation in several optical anisotropic media based on the obtained FLC alignment model.

    Dependences of turbidity on film thickness in polymer dispersed liquid crystal (PDLC) films are measured for droplet-type, which liquid crystal (LC) droplets were dispersed in polymer matrix, and a network-type, which contains a three-dimensional polymer network in LC. In the droplet-type films, the characteristics of light extinction at the interfaces with substrate differ from it at the middle layer. The turbidity in the interfaces is lager than middle layer and greatly dependent on LC droplet size. In other side, in the network-type films, the turbidity is bigger than the droplet-type. The dependence of extinction on the wavelength is much small. The relationship between the film structure and scattering properties was investigated experimentally.

    A variable neutral density filter using guest-host liquid crystal devices we investigated for color video image sensing. The liquid Crystal device contains black dichroic dyes whose absorption is controlled by voltage applied to the device. The fabricated filter keeps the spectral balance of transmitted light almost constant in the visible wavelength range, when the light transmittance is varied by the applied voltage. It exhibited a high extincion ratio of 70:1 and response time of 50ms when it was driven by 20V. The color temperature shift of the transmitted light was then suppressed to less than 200K at 5000K. We also demonstrated the automatic light exposure system using it without aperture control, to keep video signal level constant for a great change in the illuminance of objects to be captured.

    The morphology of fine polymer network formed in ferroelectric liquid crystal was observed with an optical microscope and a scanning electron microscope, and its formation mechanism was studied for obtaining the rigid polymer network supporting substrates of the liquid crystal devices. It was found that the polymer made from mono-functional acrylate monomer by photopolymerization-induced phase separation forms a small fiber morphology with fibril aggregation, which is aligned in parallel to the liquid crystal molecular orientation controlled by alignment layers. The polymer fiber became shout with the increase of the monomer concentration. The self-assembling phenomenon is considered to be induced by the interfacial tension of liquid polymer component in polymerizing, and the transient morphology of polymer in phase separation process is rapidly fixed by the polymer curing. By forming the aligned polymer fiber network, the spatial grayscale capability was obtained due to the polydomain structure of liquid crystal, and high contrast ratios over 100:1 are achieved for each primary color because of good uniformity of ferroelectric liquid crystal alignment.

    We have developed a new automatic reflected-light reducing system using polarization sensors and a liquid crystal polarizing filter. The system automatically reduces reflected light by driving the liquid crystal polarizing filter according to the polarization direction of incident light which is detected by the polarization sensors. In experiments with polarized incident light, the system is operational if the ratio of polarized light intensity to the total light intensity is over 25%. It is confirmed that the liquid crystal polarizing filter driven with the polarization sensors is useful for image capturing. However, the sensors detect incident light out of the viewing angle of the camera lens. It is found for zooming that polarization sensors need to have the same angle as the camera lens.

    We measured the viewing angle characteristics of polymer-stabilized ferroelectric liquid crystal (PSFLC) devices which contain rigid polymer network in the liquid crystal. The devices exhibit spatial gray scale capability by the areal distribution of binary liquid crystal domains, which are separated by the fine polymer network. High contrast is obtained over wide viewing angles of more than 100° without any contrast inversion. Also we simulate the viewing angle characteristics for the in-plain switching mode, where liquid crystal molecules move in the plain parallel to the substrate. It turned out that the simulation shows the similar tendency to PSFLC devices. Wide viewing angle and high-speed gray scale capabilities should make PSFLC a promising electrooptic material for future moving picture displays.

    The morphology of polymer fiber network formed in ferroelectric liquid crystal devices was closely observed by optical and scanning electron microscopes, and the formation mechanism of the polymer was investigated for obtaining a rigid polymer structure supporting substrates. It was found that aligned polymer fibers are formed with fibril aggregation, which is induced by photopolymerization of monofunctional acrylate monomer aligned in parallel with the liquid crystal molecular alignment. As the monomer concentration increases, the polymer fibers are transformed into thicker and harder structures. This self-assembling phenomenon is thought to be induced by the interfacial tension of the liquid-state polymer with comparatively low molecular weight during the polymerization, and the transient unstable polymer morphology that appears in the phase separation process can be fixed by rapid curing of the polymer material.

    New types of light-controllable luminaires using a metal halide lamp or a Xenon lamp with a liquid crystal light shutter have been developed and demonstrated for spot or beam spot lighting of television program production. We fabricated a novel liquid crystal light shutter using a heat-resistant composite film of polymer and liquid crystal materials with a wide range of operating temperatures up to 150℃. The light shutter can modulate a strong luminous flux from the high-intensity discharge lamps, instead of a conventional mechanical shutter which has problems such as generating acoustic noise and being slow and heavy. The light modulation of the light shutter is based on a light scattering effect and the degree of scattering is controlled by the voltage applied to the shutter. It exhibits attractive features such as high transmittance, high-speed response, and high extinction ratio. The luminous intensity of an object could be varied continuously using the luminaires with the shutter, and the chromaticity deviation was drastically decreased by driving it with pulse width modulation.

    When the illumination changes from the indoor light to the sun light on the location photography by the television, the color temperature changes and the color balance of the photography picture collapses mainly. In the past, we mechanically set a camera with the color temperature revision filter which is made of colored glass or electrically collect using the color collector on the side of the camera. However, these metiod are not so good way. So, we designed and made the filter which is made of liquid device that we can control color temeprature fast and smooth.

    A free-standing gel film containing ferroelectric liquid crystal in polymer network was formed for a future flexible flat display which will implement attractive features of ease of large-size fabrication, light-weight and anti-shock panel structure. The 3μ m-thick gel film fastening transparent substrates was obtained by dispersing acrylate monomer of more than 20% concentration using photopolymerization-induced phase separation. It exhibited electrooptic response faster than 300μ s, high extinction ratio over 100, grayscale capability due to switching domain distribution. The high-speed response and physical stiffness can be consistent in it, because low-molecular weight liquid crystal molecules are separated from high polymer molecules which restrict conical switching behavior of the liquid crystal.

    A high-speed controllable polarizing filter has been developed to eliminate obstructive polarized light reflected from glass and watery surfaces for image pickup in video media program producing and marine dynamic remote sensing. In this device, the polarization plane of incident light is rotated through 0 45 90or 135by an electrically-controllable polarization rotator composed of 45and 90twisted nematic liquid crystal cells, and the polarization component of reflected light is absorbed by a fixed polarizing film. It selectively absorbs more than 80% of incident white light linearly polarized in an arbitrary direction. With the drastic reduction of reflected light, the object images hidden by the bright reflected light are clearly captured in real time. Another type of polarizing filter, using a guest-host liquid crystal cell instead of the polarizing film, controls light absorption as well as polarization angle.

    A new storage-type spatial light modulator has been developed which uses a polymer-dispersed phase-transition liquid crystal film and a photoconductor for high-brightness projection displays. The liquid crystal film containing micrometer-sized chiral nematic liquid crystal domains subdivided by a unique honeycomb polymer network functions as a memory layer for an input image. The liquid crystal domains independently maintain the binary alignment states in the opaque (light-scattering) cholesteric phase or transparent nematic phase. Grayscale images can be displayed according to the spatial distribution of the bistable liquid crystal domains. The device exhibits rapid response of a few ms and a limiting resolution of 32 lp/mm. It has the advantages of high transmittance without polarizers and ease of fabrication due to the free-standing liquid crystal film.

The liquid crystal droplets are formed to be small and uniform by precoating an organic film(PVA) on the substrate. The droplet size and electro-optic properties are strongly influenced by the band width of UV light.

    A compact luminaire consisting of a 270-W metal halide lamp and a new light shutter using a composite film of liquid crystal and polymer, which can operate in the wide range from room temperature to more than 100°C, has been developed for TV-lighting. The illuminance can be controlled approximately from 100 lux to 10000 lux by the voltage applied to the light shutter. The high-speed response (3 ms) of the light shutter allows a stroboscopic lighting effect to be obtained by applying a pursed voltage. A new lighting effect is also achieved by modulating the high-intensity light by electrical sound signal. This compact lighting system will be useful for various applications such as TV or movie locations, stages, and outdoor exhibitions.

    The basic characteristics of a medium-wave broadcasting monopole antenna erected on an isolated, axially symmetric lossy mountain above a perfectly conducting plane are investigated experimentally by using a small scale model (1000 : 1). The experimental mountain model consists of a hemisphere and a truncated cone filled with a lossy gelled medium called Asron. The input impedance, the radiation efficiency, tne gain, and the radiation patterns are measured. Some of these measured results are compared with the theory. The model experiments generally confirm the theory that an antenna erected on a mountain top can improve the radiation efficiency and the gain compared with the case where the antenna is erected on a plane when the length of the antenna and the height of the mountain are moderate and appropriate.

    Optical compensation of flexible vertical-aligned LCDs was achieved for wide viewing angle. Optical simulation clarified that viewing angle range can be improved by optical compensation considering optical anisotropy of plastic substrates. We then obtained good contrast ratio of 650:1 and wide viewing angle of 160° by fabricating devices.

    We are researching fabrication of flexible OLED display using printing methods. In this report, we successfully fabricated the reflection electrode for top emission of OLED by using the screen-printed Ag electrode. This is one of the basic technologies for fabricating an all-printed large area or high definition flexible OLED display.

    We investigated the dependence of InGaZnO (IGZO) thin-film transistor characteristics on IGZO thickness. The ON current was nearly constant with respect to IGZO thickness. The threshold voltage shifted negatively with increasing IGZO thickness because a thicker IGZO film requires a higher negative gate voltage for it to be fully depleted.

    Bending tolerance of InGaZnO4 (IGZO) TFTs formed on an ultrathin polyimide film was evaluated. The IGZO layer and a SiOx gate insulator were formed at room temperature and annealed at 130℃ in ambient air. We found that the TFT characteristics were maintained even after the device was rolled at a small radius of 1mm.

    A new accurate and computationally efficient device simulator for amorphous IGZO TFTs is developed. The simulator takes into account the influence of trap states in the band gap to reproduce the gradual increase of the subthershold current. Calculations using the simulator produce results that are good agreement with measurements over a wide range of gate voltage.

    An 8-inch flexible AMOLED display driven by oxide-TFTs was successfully fabricated. Solution-processed organic materials were used as the gate insulator and the passivation layer of the backplane. Phosphorescent polymers were also used as the OLEDs. The fabricated flexible display showed clear color moving images.

    Liquid crystal materials with self-assembly molecular alignment have light modulation for polarized light in non-emissive flat-panel displays. The liquid crystal alignment structures create various electro-optic effects. The variation and flexibility in combination of the liquid crystal device and illumination light source also enable to apply to display usages in various illumination environments. The liquid crystal is useful to next-generation display technology including flexible display.

    We have formed polymer walls supporting substrates in cholesteric liquid crystal using a photopolymerization-induced phase separation method for a flexible electronic paper display. We also dispersed fine polymer networks in the cholesteric liquid crystal to suppress twist pitch change for temperature change. We obtained a design method for the cholesteric liquid crystal and polymers, by studying the twist pitch dependence on polymer forming conditions using a wedge cell. The device structure with polymer walls and networks is useful to a flexible reflective display with excellent thermal stability.

    An organic LED panel and a field-sequential color LCD panel driven by organic TFTs (OTFTs) have been fabricated using plastic films. Large W/L ratio of OTFT makes it possible to obtain sufficient write operation to the pixel within a short selection time for the moving picture with frame rate of 60Hz in both panels. Good display characteristics are confirmed on the rate. However, feedthrough voltage should be lowered to reduce the driving voltage and to increase the luminance in the future.

    We clarified the cholestric liquid crystal alignment structures induced by stretched polymer filaments. The fine polymer filament was formed by exfoliating nonwoven cellulose cloth. The filament was sandwiched between glass substrates with parallel alignment layers, and cholesteric liquid crystal material was then filled in the substrate gap. The microscopic observation of the liquid crystal microtextures revealed that the polymer surface anchors liquid crystal directors to the filament direction, and the helix of cholesteric liquid crystal is fixed to be perpendicular to the filament direction (double twist tube structure).

    Organic TFT (OTFT)-driven 16×16 color-liquid crystal display panel on a flexible plastic film has been developed. We fabricated low voltage operation bottom-contact (BC) OTFT with anodized Ta_2O_5 gate insulator by using photolithography method. The OTFT showed a operating drain voltage of -5V, a carrier mobility of 0.3cm^2/Vs, and a current on/off ratio of over 10^6. We integrated the Film LCD, which has a fast response speed less than 1 msec, with OTFT array by printing method.

    We fabricated an A4-sized flexible display using an ferroelectric liquid crystal (FLC) and flexible backlight sheet. The backlight sheet was composed of side lights of three-primary-color LED chips and a flexible-polymer thin light guide plate to obtain high flexibility. To improve the molecular alignment of a composite film of the FLC and fine polymer fibers near polymer walls, plastic substrates with low thermal distortion was used and a compounding ratio of liquid crystal and monomer was adjusted. A fabricated A4-sized flexible display exhibited color moving images by driving with an active matrix technique using external switch transistor array based on a field-sequential-color method.

    Molecular alignment disorder of polymer walls in a flexible ferroelectric liquid crystal (FLC) display was improved by controlling temperature range of nematic phase of the FLC. The polymer walls were formed by ultraviolet irradiation to nematic phase FLC/monomer solution through a photomask. The polymer alignment disorder was generated by the phase transition from nematic phase to smectic phase of the solution due to decrease of monomer component in the solution. Temperature range of the nematic phase was expanded by doping nematic liquid crystal (NLC) to the FLC/monomer solution to avoid the nematic-smectic phase transition. The expansion of the temperature range was approximately 20℃ at monomer concentration of 15wt%. The level of the dark state of the FLC display with NLC doping became less than half of that without NLC.

    We could control morphology and alignment of pentacene single crystals which were segregated in liquid crystal. We fabricated liquid crystal / pentacene solution cells with different alignment layers and with various thickness to control segregation of pentacene single crystal in the cells. We also tried to induce crystal segregation under applied voltage. According to these experiments, we obtained the different morphology and alignment of crystals. Furthermore, we confirmed molecular alignment of pentacene single crystal based on Raman-scattering spectral microscopy.

    We propose a novel formation method of polymer walls in liquid crystal (LC) layer using wetting and molecular alignment. The polymer walls are obtained by thermal phase separation of an LC/polymer solution between substrates with polyimide films patterned by short-wavelength ultraviolet irradiation using a photomask. The difference of the wetting characteristics between the polyimide films and the substrate surface causes the coalescence of the LC droplets on the patterned polyimide films when the phase separation is induced. Consequently the polymer walls are formed on the substrates without the polyimide films. In addition, the po]ymer walls become sharp by using rubbed polyimide films because the nucleation of the growing LC droplets concentrates on the polyimide films. It is thought that the increase of the alignment order of the LC molecules in the solution near the rubbed polyimide films promotes the LC molecular aggregation which becomes the growth nuclei of the LC droplets.

    In order to realize flexible displays, we fabricated an A4-sized ferroelectric liquid crystal (FLC) display device using microcolor filters mounted on a plastic substrate. The color filters and ITO electrodes were formed on a glass substrate, and then transferred to the plastic substrates. This technique can form flat surface of the substrate and make fine patterning of the color filters and ITO electrodes. Then, an FLC/monomer solution film was uniformly coated on the substrate by flexographic printing method to form a large-size FLC/polymer composite film sustaining the plastic substrates. A fabricated A4-sized device with color pixels presented images even when the device was bent.

    We have found that liquid crystal solvents can control single crystal morphology of segregated pentacene organic semiconductor, which is expected to have high charge mobility. Original pentacene powder was dissolved in heated liquid crystal, and the solution was confined in a cell with polyimide alignment layers. Different-morphologies pentacene segregation was confirmed in cooling the cell with various pentacene concentration ratios. The rubbing process of the alignment layer promoted growth of large lozenge single crystals in the cell. The lozenge morphologies were classified as pyramidal and thin flat plate shapes. The flat one is useful for electronic device applications

    A flexible liquid crystal hologram was prepared as a novel type of holographic materials. Polycarbonate films covered with a polyimide were employed as a substrate, and toluene solution of a polymer azobenzene liquid crystal (PALC) was coated on the rubbed substrate, resulting in a flexible PALC film. We attempted the formation of gratings and holographic image storage of 3-D objects into the flexible film. A clear and bright 3-D image was successfully reconstructed even in the bent film.

    A flexible field-sequential-color matrix display has been developed using an A4-sized plastic-substrate-based monostable ferroelectric liquid crystal panel, in which image pixels are driven by an active matrix technique using an outer switch transistor array circuit. The black matrix and transparent electrode patterns were formed on a large flexible plastic substrate by transfer method, and then the composite film of the liquid crystal and micropolymers suspending the substrates was formed by printing and phase separation processes. The color display operation with 24 x 16 image pixels was obtained by illuminating the image pixels uniformly with intermitted light from RGB LEDs and by driving the pixels according to each color illumination.

    We fabricated an organic TFT (OTFT)-driven 5×5 polymer-dispersed liquid crystal(PDLC) display cells on a flexible plastic substrate. The OTFT showed the carrier mobility of 0.4cm^2/Vs and the ON/OFF ratio of 10^5. We optimized the fabrication process of the cells, and confirmed reflective display operation of the cell with a low driving voltage of 12-15 Volts.

    We fabricated flexible reflective ferroelectric liquid crystal (FLC) devices monostabilized by polymer walls and networks. To control the thickness of the thin composite film of FLC and polymer, etched spacers were formed on a plastic film substrate by photolithography. Subsequently, the substrate was uniformly coated with an FLC/monomer solution by flexographic printing method. An insulator layer was also formed on another substrate to avoid short circuit between ITO electrodes. After lamination of the coated substrate and the substrate with the insulator layer was performed, the polymer walls and networks were formed in the FLC by two-step irradiation of ultraviolet light. A fabricated reflective FLC device sandwiched by a polarizer and a mirror film exhibited mechanical flexibility and light modulation with grayscale capability.

    For the π-cell, typically the bend configuration that exhibits a very fast response speed, the initial splay-to-bend transition has been the cause of a number of problems. We demonstrate a novel design for a π-cell using an in-situ fabricated micro-celled structure, which comprises of polymer walls that can be stabilized into a bend configuration in the initial stage. These devices are formed from a mixture of nematic liquid crystal and multifunctional monomer by a local photopolymeriztion process using non-uniform UV irradiation though a patterned photomask, which separates the formation of the liquid crystal region and the polymer region. In a π-cell containing a large number of mcro-celled polymer structures, which were arranged in a square grid consistent with the photomask pattern, the bend configuration of the liquid crystal was stabilized by a lock-in effect based on the free energy.

    We fabricated a high-contrast twisted-alignment guest-host liquid crystal device with small twist angle. By using the liquid crystal having a low refractive index anisotropy, the twist angle of this device containing dichroic dye in the liquid crystal can be reduced without meetting Mauguin limit condition. The device has no polarization rotation effect for incident light. As a result, the intensity of transmitted light can be decreased in dark state, because both incident light components of two crossed polarizations are efficiently absorbed. Through the optical simulation and measurement of electrooptic effects, it was confirmed that the dark-state transmittance is reduced by low optical anisotropy and appropriate twist angle. It was also found that response time of the device is not increased when the twist angle is increased, if the angle is under 180° .

    We propose a novel bend-alignment liquid-crystal(LC) cell with a three-dimensional aligned polymer, which can stabilize the bend state in the initial stage. This bend-cell was fabricated by using photo-polymerization-induced phase separation under an electric field. As the mixed solution of the liquid-crystalline monomer and LC sandwiched between the two substrates was subjected to an electric field and partially irradiated with ultraviolet light, the monomer aligned with LC molecules was polymerized to form a vertical wall with respect to the substrate. Consequently, the bend-alignment of the LC was stabilized by both interfaces of the polymer wall and substrate. The fabricated device exhibits great potential for display applications, such as no need of the initialized voltage to transit form spray to bend state, and no operating bias voltage above the critical voltage to keep the bend-state.

    Dielectric properties of some types of nematic liquid crystal(LC) were measured using coaxial lines in microwave frequency range. The measured dielectric properties were evaluated in terms of the types of LC, so that one of the indications to know what type of LCs should be selected for material of microwave devices was obtained. The results show cyano-containing LCs have large birefringence and low loss tangent, fluoro-containing LCs have low loss tangent, and negative nematic LCs have small birefringence and large loss tangent. In addition, dielectric properties of LCs were also measured by the resonator method to verify the coaxial lines method.

    We have proposed and fabricated a thin ferroelectric liquid crystal device with large cone angle (45°) , and studied its molecular switching behaviors. In the device, the molecular alignment direction is stabilized in rubbing direction of two polyimide alignment layers coated on substrates, by enhancing the influence of the anchoring effect of the alignment layers, where the rubbing strength is heightened and the liquid ciystal thickness (1μ m) is small. The molecular alignment change from the rubbing direction occurs according to applied voltage, resulting in producing a V-shape electrooptic effect with continuous light modulation. As the alignment defects could be reduced by decreasing liquid ciystal thickness, the device obtained a high contrast ratio of 250. We also considered a model of molecular alignment structure through measurement and simulation results of viewing-angle properties of the device.

    New types of light-controllable luminaires using a metal halide lamp or a xenon lamp with a liquid crystal light shutter have been developed and demonstrated for spot or beam spot lighting of television program production. We fabricated a novel liquid crystal light shutter using a heat-resistant composite film of polymer and liquid crystal materials with a wide range of operating temperatures up to 150°C. The light shutter can modulate a strong luminous flux from the high-intensity discharge lamps, instead of a conventional mechanical shutter which has problems such as generating acoustic noise and being slow and heavy. The light modulation of the light shutter is based on a light scattering effect and the degree of scattering is controlled by the voltage applied to the shutter. It exhibits attractive features such as high transmittance, high-speed response, and high extinction ratio. The luminous intensity of an object could be varied continuously using the luminaries with the shutter, and the chromaticity deviation was drastically decreased by driving it with pulse width modulation.

    We studied smectic layer structures of ferroelectric liquid crystal (FLC) formed in elongated small spaces surrounded by molecule-aligned polymer walls and rubbed polyimide alignment layers. The polymer walls, which are parallel to a rubbing direction and upright to the alignment layers, were formed by photopolymerization of aligned monomer under patterned ultraviolet-light irradiation. We observed the alignment textures of the FLC between the polymer walls with a polarizing microscope. As a result, as the interval between the polymer walls decreased, it was found that the smectic layer structure was changed from vertical-plane bending alignment (chevron structure) observed with a conventional surface-stabilized FLC into horizontal-plane bending. It is thought that the smectic layer structure deformation is decided by the competition of the anchoring effects of the alignment polyimide layers and the molecule-aligned polymer walls.

    We have studied the relationship between bent smectic layers of ferroelectric liquid crystal(FLC)stabilized by polymer fibers and molecular-alignment bistability, and realized the memory effect of the FLC by controlling the smectic layer structure. In forming the aligned polymer fibers with photopolymerization-induced phase separation, high pretilt alignment layers were used, so that the bending direction of FLC alignment was uniformed in cross-sectional plane. When the phase of FLC materials was changed from smectic A to smectic C^*, we applied ac voltage to the formed FLC/polymer composite film to stabilize cone axis of the FLC switching in rubbing direction. The bending of smectic layers in device plane was reduced, and the uniform layer structure allowed the memory effect of the device. The memory function accompanied the grayscale capability because of spatial distribution of bistable FLC domains with various threshold voltages.

    We have developed a printing fabrication process for large and light-weight liquid crystal devices and have fabricated ferroelectric liquid crystal (FLC) devices with plastic film substrates. The proposed process is based on a flexographic printing method. FLC/monomer solution coated on an anilox roll was uniformly deposited on the letter press and then transferred to the surface of the substrate from the letter press. This method is able to control thickness and printing area of the solution on the substrate. Pressure of a roller for lamination was adjusted so that an upper substrate was pressed onto spacers dispersed in the solution. Formation of air bubble in the solution was reduced by heating upper and lower substrates to 50℃. And then the laminated cell was pressed by a glass to prevent curling of the substrates and to obtain uniform cell temperature. After the cell was irradiated by ultraviolet light, polymer network which supports the substrates was formed in the FLC. Alignment of liquid crystal molecules was observed. Light modulation effects including grayscale capability were also observed when voltage was applied between electrodes of the devices.

    A free-standing composite film of ferroelectric liquid crystal (FLC) and aligned ploymer fiber networks supporting plastic thin substrates is expected to be applied to a large and light-weight sheet display in future. We clarified the FLC alignment structures formed between the fine polymer fibers, by polarizing microscopic study and X-ray diffraction measurements. It was found that bending of smectic layers of FLC is induced in both the film and cross-sectional planes at the phase transition from smectic A to smectic C of FLC. The light transmittance properties of the composite film between crossed polarizers was analyzed by light propagation simulation in several optical anisotropic media based on the obtained FLC alignment model.

    We have developed a new automatic reflected-light reducing system using polarization sensors and a liquid crystal polarizing filter. The system automatically reduces reflected light by driving the liquid crystal polarizing filter according to the polarization direction of incident light which is detected by the polarization sensors. In experiments with polarized incident light, the system is operational if the ratio of polarized light intensity to the total light intensity is over 25%. It is confirmed that the liquid crystal polarizing filter driven with the polarization sensors is useful for image capturing. However, the sensors detect incident light out of the viewing angle of the camera lens. It is found for zooming that polarization sensors need to have the same angle as the camera lens.

    Dependences of turbidity on film thickness in polymer dispersed liquid crystal(PDLC)films are measured for a droplet-type, which liquid crystal(LC)droplets were dispersed in polymer matrix, and a network-type, which contains a three-dimensional polymer network in LC. In the droplet-type films, the characteristics of light extinction at the interfaces with substrate differ from it at the middle layer. The turbidity in the interfaces is lager than middle layer and greatly dependent on LC droplet size. In other side, in the network-type films, the turbidity is bigger than the droplet-type. The dependence of extinction on the wavelength is much small. The relationship between the film structure and scattering properties was investigated experimentally.

    The morphology of fine polymer network formed in ferroelectric liquid crystal was observed with an optical microscope and a scanning electron microscope, and its formation mechanism was studied for obtaining the rigid polymer network supporting substrates of the liquid crystal devices. It was found that the polymer made from mono-functional acrylate monomer by photopolymerization-induced phase separation forms a small fiber morphology with fibril aggregation, which is aligned in parallel to the liquid crystal molecular orientation controlled by alignment layers. The polymer fiber became stout with the increase of the monomer concentration. The self-assembling phenomenon is considered to be induced by the interfacial tension of liquid polymer component in polymerizing, and the transient morphology of polymer in phase separation process is rapidly fixed by the polymer curing. By forming the aligned polymer fiber network, the spatial grayscale capability was obtained due to the polydomain structure of liquid crystal, and high contrast ratios over 100:1 are achieved for each primary color because of good uniformity of ferroelectric liquid crystal alignment.

    This paper presents simulated and experimental results of a microwave variable delay line using a liquid crystal. Except for large insertion loss, the delay characteristics are flat over a wide microwave frequency range. Analyses of the attenuation of the delay line indicate that the large insertion loss is mainly caused by conductive loss of the microstrip line. Increasing the thickness of the liquid crystal reduces the loss. We suggest using, for example, polymer-dispersed liquid crystals for the thick liquid crystal layer because controlling the molecular orientation of these liquid crystals is easy.

    We measured the viewing angle characteristics of polymer-stabilized ferroelectric liquid crystal(PSFLC)devices which contain rigid polymer network in the liquid crystal. The devices exhibit spatial gray scale capability by the areal distribution of binary liquid crystal domains, which are separated by the fine polymer network. High contrast is obtained over wide viewing angles of more than 100゜ without any contrast inversion. Also we simulate the viewing angle characteristics for the in-plain switching mode, where liquid crystal molecules move in the plain parallel to the substrate. It turned out that the simulation shows the similar tendency to PSFLC devices. Wide viewing angle and high-speed gray scale capabilities should make PSFLC a promising electrooptic material for future moving picture displays.

    We developed a liquid crystal filter containing dichroic dyes, which continuously control color temperature of the transmitted light in real time. The filter was designed and fabricated based on Planck radiation law and Lambert-Beer's law, as a result, it exhibited the conversion range of color temperature form 2530K to 4450K, which was equivalent to that of a conventional color glass filter, and response time of 80 ms. It is confirmed that the color valance of pickup image could be corrected using a camera with the filter. This filter is especially useful for television location shooting in which illumination light source changes from incandescent lamp to solar light and the color temperature of the illumination varies.

    A free-standing gel film containing ferroelectric liquid crystal in polymer network was formed for a future flexible flat display which will implement attractive features of ease of large-size fabrication, light-weight and anti-shock panel structure. The 3μm-thick gel film fastening transparent substrates was obtained by dispersing acrylate monomer of more than 20% concentration using photopolymerization-induced phase separation. It exhibited electrooptic response faster than 300μs, high extinction ratio over 100, grayscale capability due to switching domain distribution. The high-speed response and physical stiffness can be consistent in it, because low-molecular weight liquid crystal molecules are separated from high polymer molecules which restrict conical switching behavior of the liquid crystal.

    A type of 3D camera was proposed and the performances were evaluated. The camera adds the depth information to each pixel of an ordinary two dimensional television image. The camera uses a combination of a high-speed shutter with intensity modulated illuminator. As a result of experiments, it was verified that the depth information was obtained independent of the reflectivities or the shape of the objects. The results of experiments using several kinds of targets suggest a possibility developing this to a 3D TV camera.

    In order to improve microscopic-image display properties of a liquid crystal device, we fabricated a surface-stabilized ferroelectric liquid crystal cell with the optical alignment process using polarized deep ultraviolet excimer light with short wavelength. Using the liquid crystal cell with finely-patterned transparent electrodes, the spatial dispersion of threshold voltage for bistable switching became small without microscopic alignment defects, and the high limiting resolution of over 400 line pairs/mm was recognized.

A fabricated polarizer using 45° and 90° TN-LC cells, which rotate polaization direction of incident light with 0°, 45°, 90° or 135°, can eliminate more than 80% of polarized light for all polarization angles.
