    摘要: A polymer film with a refractive index of n.sub.D .gtoreq.1.60, an Abbe number of .nu..sub.D .gtoreq.30.0 and a glass transition temperature of Tg=60.degree. to 160.degree. C. is oriented at least in one direction to provide an oriented film. It is arranged that this oriented film has a retardation value of R=60-1000 nm and a wavelength dispersion value of .nu..sub.RF .gtoreq.1.10. An optically compensating film comprising this oriented film or an optical compensator comprising the oriented film and an optically isotropic film laminated at least on one side thereof is used for color compensation in a liquid crystal display panel. In this manner, a liquid crystal display device solving the long-standing problems of coloration and low contrast ratio is obtained.

    摘要: A laminate for protecting an optical recording layer of an information recording member, particularly an information recording layer of an optical card, is disclosed. An organic solvent-resistant synthetic resin layer (12) is provided on the surface of a transparent and optically isotropic synthetic resin sheet (11), said surface being covered with an information recording layer. The synthetic resin layer (12) is composed of a crosslinkable phenoxy ether resin, a polyparabanic acid resin or a polyacrylonitrile resin and is formed by casting. Since the laminate for protecting an optical recording layer has the above-described laminate structure, it has good transparency, good optical isotropy, good mechanical strengths, good hardness, good solvent resistance, low heat conductivity, good heat resistance, good moisture absorption resistance, gas barrier property, etc. and can be put into practice also in respect to production cost.
