Laminate for protecting optical recording layer

A liquid crystal display panel incorporating an optical phase shifting substrate which comprises a liquid crystal cell, a pair of polarizing sheets disposed on opposing sides thereof, and a couple of substrates each having a transparent electrode layer, one of the substrates being either an optical phase shifting single oriented synthetic resin film or a laminate film comprising an optically isotropic amorphous film laminated to at least one side of the above optical phase shifting film and the other substrate being either a single-layer or multi-layer optically isotropic amorphous film or a glass sheet.

Liquid crystal display panel incorporating an optical phase shifting

A flexible optical recording material in the shape of tape or floppy disk comprising an optically isotropic laminate (A) comprising at least one thermoplastic gas-impermeable synthetic resin film layer (1) and at least one cured crosslinking resin layer (2), said layers having been formed by casting and having a retardation value of not less than 80 nm as a whole, and a recording layer (B) disposed on at least one side of said optically isotropic laminate.

Flexible optical recording material in the shape of tape or floppy disk

A liquid crystal display panel electrode plate having a transparent electrode on at least one side is described. 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.
