Optically compensating film, optical compensator and liquid crystal display

A liquid crystal display comprising:

• (a) a liquid crystal cell;
• (b) a pair of polarizers disposed on respective sides of said liquid crystal cell;
• and
• (c) at least one optically compensating film interposed between said liquid crystal cell and one polarizer of said pair of polarizers, wherein said optically compensating film comprises:
• an oriented film obtained by stretching, in at least one axis, a polymer film having a refractive index n.sub.D .gtoreq.1.60, an Abbe number .nu..sub.D .ltoreq.30.0, and a glass transition temperature of T.sub.g =60.degree. to 160.degree. C.

A liquid crystal display comprising:

• (a) a liquid crystal cell;
• (b) a pair of polarizers disposed on respective sides of said liquid crystal cell;
• and
• (c) at least one optical compensator interposed between said liquid crystal cell and one polarizer of said pair of polarizers, wherein said optical compensator comprises:
• (1) at least one optically compensating film which is an oriented film obtained by stretching, in at least one axis, a polymer film having a refractive index .gtoreq.1.60, an Abbe number .nu..sub.D .ltoreq. 30.0, and a glass transition temperature of T.sub.g =60.degree. to 160.degree. C., and
• (2) at least one optically isotropic film laminated to said optically compensating film.
