ABSTRACT:
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.
