Abstract
A transparent base plate supports a first compensating layer, which is adapted to compensate for a phase difference due to liquid crystal molecules having undergone normal orientation in a liquid crystal layer of a TN liquid crystal display device, and second compensating layers, which are adapted to compensate for the phase difference due to the liquid crystal molecules having undergone hybrid orientation in the liquid crystal layer. Each of the second compensating layers is constituted of one of oblique incidence vacuum deposited films, which are formed on opposite surfaces of the base plate with oblique incidence vacuum evaporation of an inorganic material. An azimuthal angle and/or a polar angle of a direction of vacuum evaporation with respect to a plane of vacuum evaporation is set to be different between the second compensating layers.
