    摘要: A liquid crystal composition comprises liquid crystal molecules and an alignment promoter. The alignment promoter is represented by the formula (I). (Hb—)mL(—Bu)n  (I) In the formula (I), Hb is a hydrophobic group selected from the group consisting of a fluorine-substituted alkyl group having 1 to 40 carbon atoms, a fluorine-substituted aryl group having 6 to 40 carbon atoms, an alkyl group having 6 to 60 carbon atoms and an alkyl-substituted oligosiloxanoxy group having 1 to 60 carbon atoms. Bu is a bulky group showing an excluded volume effect and comprising at least two rings. L is an (m+n)-valent linking group. Each of m and n is independently an integer of 1 to 12.

    摘要: A circularly polarizing plate comprises a linearly polarizing membrane and a quarter wave plate. The quarter wave plate comprises an optically anisotropic layer A and an optically anisotropic layer B. The quarter wave plate has such an optical characteristic that a retardation value essentially is a quarter of a wavelength when the retardation value is measured at the wavelength of 450 nm, 550 nm and 650 nm. One of the optically anisotropic layers A and B is a layer made from liquid crystal molecules, and the other is a polymer film or a layer made from liquid crystal molecules.

    摘要: A phase retarder comprises two optically anisotropic layers A & B. The optically anisotropic layer A essentially gives the phase retardation of &pgr; at wavelength of 550 nm, and the optically anisotropic layer B essentially gives the phase retardation of &pgr;/2 at wavelength of 550 nm. The layers A and B are laminated so that the retarder has such an optical characteristic that a retardation value per wavelength is within the range of 0.2 to 0.3 at each wavelength of 450 nm, 550 nm and 650 nm. The total thickness of the layers A and B is within the range of 500 nm to 20 &mgr;m.

    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.
