    摘要: An optically anisotropic cellulose ester film is disclosed. The film contains a discotic compound in an amount of 0.01 to 20 weight parts based on 100 weight parts of cellulose ester. The film has a Rth550 retardation value in the range of 60 to 1,000 nm. The cellulose ester film can be used in an optical compensatory sheet, an ellipsoidal polarizing plate and a liquid crystal display.

    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: An optical compensation sheet favorably employable for a liquid crystal display has an optical anisotropic layer which is composed of a polymer of a non-chiral discotic liquid crystal compound having a polymerizable group and a chiral compound. The non-chiral discotic liquid crystal compound is preferably aligned at an angle between 45° and 90° to a plane of the compensation sheet and under a twisted orientation at an angle between 90° and 360°.
