    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.

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.

This electrode plate comprises an optically non-rotatory transparent film substrate layer having a retardation value of not more than 30 nm as formed from a polycarbonate resin, polyether sulfone resin, polysulfone resin or polyarylene ester resin, and anchor layer formed from a solution or dispersion of an anchor agent in aqueous medium as disposed on at least one side of the substrate layer, and one or more protective layers of gas-impermeable resin or/and cured crosslinkable resin as disposed on the anchor layer. This electrode plate is optically transparent to visible light, optically isotropic, resistant to moisture, chemicals, liquid crystals and gas-impermeable.
