20080278662 | PHASE DIFFERENCE CONTROL COMPONENT HAVING COLUMNAR MATERIAL - The invention has for its object the provision of a phase difference control component that, albeit comprising a phase difference control layer formed of a polymerizable liquid crystal, enables a given spacing to be maintained between opposite substrates, etc. A phase difference control component | 11-13-2008 |
20080303985 | Liquid Crystal Composition, Color Filter and Liquid Crystal Display Apparatus, and Method of Forming Phase Difference Layer - An object of the invention is to provide a liquid crystal composition intended to be applied to the surface of a base material to form a phase difference layer, the liquid crystal composition being capable of forming a phase difference layer well indicating homeotropic orientation without the presence of an oriented film, even if the liquid crystal composition is directly applied to the base material surface, as well as a phase difference layer formed by the liquid crystal composition, a color filter and a liquid crystal display apparatus using the phase difference layer, and further a method of forming the phase difference layer. To a liquid crystal composition containing one kind or two or more kinds of crosslinking liquid crystal compounds is further added at least an amino-based silane coupling agent to prepare a liquid crystal composition. The liquid crystal composition is directly applied to the surface of a base material to orient the crosslinking liquid crystal compound on the base material surface in a direction perpendicular to the base material surface, and then the resulting material is crosslinking polymerized to form a phase difference layer. | 12-11-2008 |
20090109376 | Liquid Crystal Display Device - The invention intends to provide a liquid crystal display device that, even when a liquid crystal is fixed without completely maintaining a homeotropically aligned state, may effectively inhibit light from leaking. | 04-30-2009 |
20090185121 | Display base having a retardation control function with a high voltage holding ratio - A display board with a retardation control function has a retardation control layer containing liquid crystalline polymers with a fixed orientation, and a liquid crystal layer. The display board has a voltage holding ratio of 90% or higher after a forced impurity extraction is performed on the display board with the retardation control layer in contact with the liquid crystal layer, and application of a voltage to the liquid crystal layer. The display board is capable of providing a high quality display while preventing a drop in the voltage holding ratio attributed to impurities mixed into the liquid crystal layer, and thus preventing the occurrence of display defects, such as flickering. | 07-23-2009 |
20090195734 | Liquid Crystal Composition, Color Filter and Liquid Crystal Display - There is provided a liquid crystal composition capable of inexpensively and easily forming a phase difference layer excellent in mechanical strength such as hardness and in substrate adhesion properties, a color filter using the same, and a liquid crystal display apparatus using the color filter.

20100165256 | Optical Member With Retardation Control Function And Liquid Crystal Display - The invention provides a retardation-controlling optical member that includes a retardation layer obtained by aligning and fixing crosslinkable liquid crystal molecules and columnar structures disposed on the retardation layer. When a liquid crystal cell is formed by use of the retardation-controlling optical member, the columnar structures are effectively inhibited from subsiding in the retardation layer to locally make the cell gap smaller even when pressure is externally applied in a thickness direction of the liquid crystal cell. | 07-01-2010 |
20100231836 | PHASE DIFFERENCE CONTROL MEMBER, LIQUID CRYSTAL DISPLAY AND LIQUID CRYSTAL MATERIAL COMPOSITION FOR FORMING PHASE DIFFERENCE LAYER - Provided is a phase difference control member which has a function to suppress a surface step amount and an excellent optical compensation function for the optical phase difference caused by a deflection plate. In the phase difference control member, the phase difference layer has an optical axis standing against the surface having a normal in the thickness direction of the phase difference layer and a surface step amount T of the phase difference layer is smaller than 500 nm. When the phase difference layer has refraction factors nx, ny nz in the direction of the X axis, Y axis, and Z axis, the nx, ny nz for the light of wavelength 589 nm and a coefficient P are in the relationship of P=(nz−((nx+ny/)2)) and the coefficient P and a thickness d (nm) of the phase difference layer satisfy the following expressions: 0.005≦P≦0.04 (Expression 1) d≦2000 (Expression 2) 10≦P×d≦40 (Expression). | 09-16-2010 |
