(57) [PROBLEMS] To provide an optical compensation sheet having excellent durability, showing a wide viewing angle, and easily manufactured. An optically compensatory sheet comprising a transparent support, an alignment film made of a polymer, and an optically anisotropic layer made of a liquid crystal compound is provided in this order. A liquid crystal compound of an optically anisotropic layer, which is chemically bonded via an interface between these layers; and an optical compensation sheet, which is advantageously used for producing an optical compensation sheet, A transparent support and a polymer layer provided thereon, and the polymer of the polymer layer is a vinyl moiety, An element having a polymer layer, characterized in that it consists of polyvinyl alcohol in which at least one hydroxyl group is substituted with a group having an oxiranyl moiety or an aziridinyl moiety. |
