<P>PROBLEM TO BE SOLVED: To provide thin film phase retardation plates for improving the viewing angle and contrast of liquid crystal displays. <P>SOLUTION: The retardation plate includes a cholesteric and an A-plate compensators. The A-plate is fabricated using a single substrate onto which a layer of polymerizable reactive mesogens (RMs) is solvent cast. Included in the RMs solution is an additive that migrates to the RM/air interface to lower the surface energy and generate an additive-rich surface layer, which in turn lowers the intrinsic tilt angle of the RMs at the air interface to between 25 degrees and about zero degrees. The solvent is evaporated and the resulting film is polymerized in the liquid crystal phase to permanently orient the liquid crystal. The resulting film may be readily separated from the substrate and shaped into any desired pattern and combined to form nobel compensators. In an alternative embodiment, a compensator having a defined splay through the thin film is formed. <P>COPYRIGHT: (C)2010,JPO&INPIT

The invention is directed to a liquid crystalline display comprising a display cell containing liquid crystalline material and a retardation layer. The retardation layer comprises a, preferably slightly cross-linked, high-molecular weight material layer and a substrate, wherein the high-molecular weight material has a nematic phase above its Tg and a dynamic viscosity at the working temperature of at least 100 Pa.s. The difference of the Tc of the high-molecular weight material and the Tc of the low-molecular weight material of the display cell (TCcell) is in the range of -30 DEG C. to +30 DEG C., preferably in the range of -20 DEG C. to +20 DEG C., and more preferably in the range of -10 DEG C. to +10 DEG C.; and the Tg of the high-molecular weight liquid crystalline material is lower than 50 DEG C. It was found that if high-molecular weight material is used with a Tc comparable with that of the, preferably low-molecular weight, liquid crystalline material of the active cell, the temperature dependency of the retardation value of the retardation layer is comparable with that of the active cell. Thus, the retardation value of the retardation layer is comparable with that of the active cell within the temperature range in which displays are used. It was further found that by cross-linking of the high molecular weight liquid crystalline material, the retardation layers according to the invention become less susceptible to pinhole forming and unwanted variation of the twist, and have improved mechanical stability.

PROBLEM TO BE SOLVED: To provide a thin film phase delay plate to improve on angle of visual field and contrast of a liquid crystal display. SOLUTION: Thsi delay plate includes a cholesteric and an A plate compensator. The A plate is produced by casting a layer of a polymerizable reactive intermediate phase material (RM) with a solvent on a single substrate 102. The RM soln. contains an additive, and the additive moves to an interface 108 between the RM and air to decrease surface energy and to form a layer containing a large amt. of the additive. The layer decreases an intrinsic tilt angle of RM on the interface 108 with air from 25 deg. to 0 deg.. By vaporizing the soln., a film is obtained as a result which is polymerized in a liquid crystal phase and the liquid crystal is permanently aligned. The obtd. film is easily separated from the substrate 102, and shaped into a desired pattern and assembled to form a compensator. The compensator having a prescribed tilt angle through a thin film 106 can be also formed.

PROBLEM TO BE SOLVED: To provide a reflection type liquid crystal display device having bright display and good visual angle characteristic. SOLUTION: This reflection type liquid crystal display device consists of a polarizing plate 1, a compensation layer 2, a liquid crystal layer 3 and a reflection plate 4. The liquid crystal layer 3 and the compensation layer 2 are reverse in the code of refractive index anisotropy from each other. The liquid crystal layer 3 when voltage is not impressed thereon or when an arbitrary voltage is impressed thereon is sliced in a thickness direction of N layers regarded to be approximately the constant direction in the bearings of the major axis of the liquid crystal molecules. The directions of the major axes of the liquid crystal molecules of the first layer from the lowermost layer side are defined as tilt angle θ1, 1 and twist angle ϕ1, 1. The compensation layer 2 consists of N layers as well and are regarded to be approximately constant in the optical axis bearings within the respective layers. The relations θ1, 1=θ2, N-1+1; ϕ1, 1=ϕ2, N-1+1 hold between the first layer of the liquid crystal layer and the (N-1+1)th layer of the compensation layer when the tilt angle θ2, 1 and twist angle ϕ2, 1 indicating the optical axis bearings in the first layer are set.

119 Optical anisotropic element and liquid crystal display element using the same JP15391293 1993-06-24 JPH0713021A 1995-01-17 MORI HIROYUKI
PURPOSE:To improve the display contrast, gradation characteristics, and visual characteristics of display colors without decreasing the front contrast by employing structure which is so twisted that the optical axes of both the surfaces of a laminate of thin films are different in direction. CONSTITUTION:The structure consists of the laminate of thin film showing optically negative uniaxiality or biaxiality close to uniaxiality and is so twisted that the optical axes of both the surfaces of this laminate are different in direction. When the optical axis of a liquid crystal cell slants from the normal direction to the top surface of the liquid crystal cell, it is predicted that an optical anisotropic body having its optical axis in the normal direction is insufficiently compensated. When it can be considered that the liquid crystal cell is a positive optical anisotropic body, a negative uniaxial optical anisotropic body is suitably used. The liquid crystal in the liquid crystal cell is twisted and oriented, so the optical anisotropic element in use preferably have twisted structure. The biaxiality close to the uniaxiality meant by the biaxiality wherein the angle between two optical axes is <=40 deg..

PURPOSE: To execute phase modulation in which there is scarcely an amplitude fluctuation by a liquid crystal cell. CONSTITUTION: An incident side liquid crystal oriented direction of a liquid crystal cell 103 is set in parallel to a transmission axis of a polarizing plate 102, and an emitting side liquid crystal oriented direction is set in parallel to a transmission axis of a polarizing plate 104. By using a TN liquid crystal cell, and setting the transmission axis of the polarizing plate in parallel to the oriented direction of an opposed liquid crystal, phase modulation in which there is scarcely an amplitude fluctuation can be executed. Also, by using this space optical modulator and executing the phase modulation in an optical information processor, one sample point of a hologram is shown by one picture element, and the number of batch processing picture elements can be improved.
