ABSTRACT:
An optical compensatory sheet is basically composed of a transparent support and an optically anisotropic layer provided thereon. The optically anisotropic layer is a layer of polymer having discotic units formed by copolymerization of a compound having at least two functional groups such as isocyanato, isothiocyanato or oxiranyl and a compound having at least two nucleophilic groups, at least one of the compounds being a discotic compound; or polymerization of a discotic compound having at least one functional group and at least one nucleophilic group. A process for the preparation of the optical compensatory sheet, a liquid crystal display and a color liquid crystal display having the optical compensatory sheet are also disclosed.
