摘要： The reflective liquid crystal display device uses only one polarizing film (10) but achieves display of bright white and achromatic color with high contrast. The twisting angle of a nematic liquid crystal is set to 45° to 90°, and the retardation value of a liquid crystal layer (17) is set to ΔnLC·dLC=0.20 µm to 0.30 µm.

摘要： A reflection liquid crystal display element having only one polarization film. The twist angle of nematic liquid crystal is 45° to 90°. The product of the birefringence of the liquid crystal multiplied by the thickness of the liquid crystal layer is 0.20 to 0.30 µm. The retardation value of the phase difference film on the polarizing film side is 0.23 to 0.28 µm. The retardation value of the phase difference film on the liquid crystal cell side is 0.13 to 0.18 µm. The Z coefficients of the two phase difference films are 0.3 to 1.0. Letting the direction in which the liquid crystal twists toward the lower substrate when viewed from above the upper substrate be positive, and if the angle between the reference line and the direction of the absorption axis of the polarizing film, the angle between the reference line and the direction of the phase retardation axis of the phase difference film on the polarizing film side, and the angle between the reference line and the direction of the phase retardation axis of the phase difference film on the liquid crystal cell side are φ P , φ F1 , φ 2 respectively, the angle φ P is 75° to 195°, φ P -φ F1 is 105° to 115°, φ P -φ F2 is 165° to 175°. Hence, high contrast display is achieved by bright white and achromatic color.

摘要： A liquid crystal display comprises, in order from the viewing side, a first glass substrate 10 carrying an electrode 12, a dichroic liquid crystal layer 16 provided with suitable alignment layers 14, 18, a half wave retarding layer 30, a quarter wave retarding layer 20, a reflector 24 and a second glass substrate 28 carrying an electrode 26. In use, in one of its states, the dichroic liquid crystal layer 16 absorbs a component of the light incident thereon, the transmitted component being plane polarised. The polarised light is incident upon the retarding layer 20 which converts the plane polarised light to circularly polarised light, this light being reflected and converted back to plane polarised light polarised in a direction perpendicular to the original plane of polarisation on returning through the retarding layer 20. Such polarised light is absorbed by the dichroic dye, no light being transmitted by the cell towards the viewer. The presence of the layer 30 improves the achromaticity of and light absorption in the dark state. In another state, the dichroic dye does not absorb, and hence does not polarise, the light, the cell then transmitting light to the viewer.

摘要： A reflective liquid crystal device comprises a polariser 1 and a mirror 2 between which are disposed several retarders 3, 4, 5. At least one of the retarders 4 is a variable liquid crystal element whose optic axis is switchable so as to switch the device between a reflective state and a non-reflective state. In the non-reflective state, the total retardance of the retarders 3, 4, 5 between the polariser 1 and the mirror 2 is equal to an odd number of quarter wavelengths for a wavelength at or adjacent the middle of the visible spectrum.

摘要： A liquid crystal device for color display utilizing a coloring phenomenon due to birefringence of a liquid crystal, which exhibits a white or achromatic color close to white at 0 V or a non-selection voltage and exhibits at least two colors at other voltages. The liquid crystal display realizes color display without using a color filter by optimizing a Δn.d value of a liquid crystal and the relationship between the Δn.d value of the liquid crystal and a retardation value (R) of an optically anisotropic member such as a phase difference film, and moreover can display white or an achromatic color close to white. In other words, the liquid crystal cell and the optically anisotropic member satisfy the following relations: Δn.d » 1 (νm), 15.5 x α2 - 40 x α + 25.1 « R - Δn.d « 15.5 x α2 - 40 x α + 25.8 (νm) where Δn.d is the product of the refractive anisotropy Δn of the nematic liquid crystal and the thickness d of the nematic liquid crystal layer, R is the sum of the products Δnj.dj, from the first layer to the ith layer, of refractive anisotropy Δn of the optically anisotropic member and the layer thickness dj (j: natural number smaller than i) of the jth anisotropic member when i (i: natural number) layers of the anisotropic member are used, and α is a ratio of refractive anisotropy of the anisotropic member at a wavelength of 450 nm to refractive anisotropy of the anisotropic member at a wavelength 590 nm.

摘要： This invention provides a complementary color polarizer using a single polarizing film (10) followed by a stack of two or more retarders (20 and 21). In a preferred embodiment, the color polarizers produce orthogonally polarized complementary primary colors. This invention further provides color filters (30 and 31) which utilize the color polarizers of this invention in combination with a polarization separator to separate orthogonally polarized colors.

摘要： It is an object of the present invention to prevent display coloration and to improve the viewing angle dependency of contrast of a liquid crystal display panel. A liquid crystal display panel is equipped with a nematic liquid crystal (LC) having a positive anisotropy of refractive index with an optical axis in the plane direction ( n x >n y =n z ). In a first version, the display panel further includes an optically anisotropic substance being made of at least one polymer film, say then a retardation compensation film (RCF), having a negative anisotropy of refractive index with an optical axis in the plane direction ( N x y =N z ). In another version, the liquid crystal is twisted at a high degree with the twist angle set at 180° to 270° and the retardation of the nematic crystal set at 0.55 µm to 0.75 µm.
