Abstract

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.
