Optische Kompensationsfolie

摘要

An optical compensatory sheet is composed of a transparent support, an orientation layer and an optically anisotropic layer. The orientation layer is made of a polymer, and the optically anisotropic layer is made of a liquid crystalline compound. The polymer of the orientation layer is chemically bonded to the liquid crystalline compound of the optically anisotropic layer via the interface of these layers. An element composed of a transparent support and a polymer layer of a polyvinyl alcohol at least one hydroxyl group of which is substituted with a group having a vinyl moiety, an oxiranyl moiety or an aziridinyl moiety, is useful for the preparation of the optical compensatory sheet.
