    摘要: A process for alignment of rod-like liquid crystal molecules comprises the steps of: forming an orientation layer for vertical alignment on a support; and forming a liquid crystal layer containing rod-like liquid crystal molecules on the orientation layer to align the rod-like liquid crystal molecules at an average inclined angle of 50 to 90°. The liquid crystal layer further contains a compound represented by the formula (I): (Hb—L1—Cy1—L2—)nCy2  (I) wherein Hb is an aliphatic group having 6 to 40 carbon atoms or an siloxanoxy group substituted with an aliphatic group having 6 to 40 carbon atoms, each of L1 and L2 is a single bond or a divalent linking group, Cy1 is a divalent aromatic group or a divalent heterocyclic group, n is 2, 3 or 4, and Cy2 is an n-valent aromatic group or an n-valent heterocyclic group.

    摘要: A liquid crystal display comprises a liquid crystal cell, a linearly polarizing membrane, a cholesteric liquid crystal layer and a quarter wave plate. The cholesteric liquid crystal layer is divided into two or more areas having different spiral pitches of cholesteric liquid crystal. The quarter wave plate comprises an optically anisotropic layer A and an optically anisotropic layer B. One of the optically anisotropic layers A and B is formed from liquid crystal molecules. The other is formed from liquid crystal molecules or made of a polymer film. The quarter wave plate gives a retardation value per wavelength within the range of 0.2 to 0.3 at each wavelength of 480 nm, 550 nm and 630 nm.

    摘要: An optical compensation sheet for improving the visual characteristics of a liquid crystal display device is disclosed with a liquid crystal display device using such a sheet. The optical compensation sheet contains at least one photopolymerization substance that is sterically or structurally isomerized by light, and has negative uniaxiality, with the optic axis of the sheet intersecting the surface of the sheet. Application of this optical compensation sheet to a TN liquid crystal display device allows it the visual angle property to be improved, thereby providing a high definition liquid crystal display device.
