摘要： PURPOSE:To display a large capacity of information at one time with a high resolution by electrifying a photoconductive layer contg. microcapsules into which a liquid crystal is sealed, then selectively exposing the layer to form latent images and impressing an AC electric field thereto to visualize the latent images. CONSTITUTION:The display medium 1 is formed by successively laminating a conductive layer 11 consisting of an ITO film or the like, an under coating layer 12, a charge generating layer 13 contg. an azo pigment, etc., and a charge transfer layer 14 contg, microcapsules sealed with the liquid crystal such as ferroelectic liquid crystal on a belt 10 consisting of polyester, etc. The surface of the medium 1 is uniformly electrified to impart transparency to the capsules in the layer 14; thereafter, the layers are selectively exposed to annihilate the charge in the exposed parts and to form the latent images. The medium 1 is then transferred to the spacing between a pair of electrodes 6 where the AC electric field is impressed to the medium 1 to convert the capsules in the late image parts 18 to the opaque capsules. The medium 1 is moved in this state to a display part and is used for the display.

摘要： PURPOSE:To provide a cell gap to assure bistable driving characteristic and to prevent the generation of an orientation defect by using thin-film transistors (TFTRs) as the spacers between substrates or dummies as the spacers between the substrates and joining the spacers and the substrate opposite to the substrate on which the spacers are formed by an adhesive agent. CONSTITUTION:The TFTRs 5 are used as the spacers between the substrates 1 and 2 or the dummies 15 corresponding to the TFTRs 5 are formed on the substrate 2 on which the TFTRs 5 are formed and said dummies 15 are used as the spacers between the substrates 1 and 2. The spacers 15 and the substrate 1 opposite to the substrate 2 on which the spacers 15 are formed are joined by the adhesive agent. The TFTRs 5 as the spacers 15 or the dummies 15 corresponding to the TFTRs 5 are, therefore, formed to the thickness of good accuracy. The cell gap which is uniformly narrow over the entire region of the liquid crystal element is thereby obtd. and the change in the cell gap between the substrates is suppressed even when casual external force is exerted on the liquid crystal cell.

摘要： PURPOSE:To provide a cell gap to assure the bistable driving characteristic of a ferroelectric liquid crystal and to obtain good display characteristics by using thin film transistors as spacers between substrates. CONSTITUTION:The side of the glass substrate 1 on which transparent electrodes 3 are formed is disposed to face the glass substrate 2 and the thin film transistors (TR) 5, 5... are used as the spacers. The glass substrate 1 is imposed on these TRs 5, 5... and further, the outside circumferential part of the substrates is sealed by a sealing material, then the two substrates are stuck to form a cell. The cell gap attains the specified value determined by the thickness of the spacers, i.e., the TRs 5, 5... in this case. The ferroelectric liquid crystal is thereafter injected into the cell to form a liquid crystal part 13 and further, polarizing plates, etc., are provided to the cell. Since the TRs 5, 5... are respectively formed to the accurate thickness, the cell gap is uniformized over the entire region of the liquid crystal element and the good display characteristic is obtd.

摘要： PURPOSE:To improve bistability of a ferroelectric liquid crystal by subjecting the ferroelectric liquid crystal to specified heat-treatment by applying an AC voltage. CONSTITUTION:A liquid crystal cell for a shutter permitting quick response, etc. is formed by injecting ferroelectric liquid crystals into a space between counter substrates. Then, the ferroelectric liquid crystals are heated by heating the liquid crystal cell until the ferroelectric liquid crystals form an isotropic liquid phase. The ferroelectric liquid crystals are then cooled slowly while applying an AC voltage to the ferroelectric liquid crystals. The ferroelectric liquid crystals are oriented uniformly and the internal bias in the liquid crystal cell is also made uniform by the heat-treatment under AC voltage. As a result, the bistability of the ferroelectric liquid crystals is improved and the storage of display in both ON and OFF state is stabilized permitting thus satisfactory bistable operation.

摘要： PURPOSE: To form a thin cell gap with good reproducibility by coating one substrate with sensitive resin and irradiating a spacer part with ultraviolet light, irradiating a display part with weak ultraviolet light from the reverse side of the substrate, and developing the display part, and forming the spacer and an oriented film at the same time.
CONSTITUTION: A transparent electrode 12 is formed on the surface of one substrate 11 and patterned, and photosensitive resin 13 is applied from above it; and the part as the spacer for forming a gap between the substrate and opposite substrate 11 is irradiated with weak ultraviolet light 17 from the reverse side of the substrate 11 and developed to form the spacer 18 and oriented film 19 at the same time. Thus, the liquid-crystal display device which has a cell gap of less than several μm is manufactured relatively easily with good reproducibility.
