Abstract
A liquid crystal display comprises a liquid crystal cell of a bend alignment mode or a homogeneous alignment mode and two polarizing elements. Each of the elements is arranged on each side of the liquid crystal cell. At least one of the polarizing elements is an ellipsoidal polarizing plate. The ellipsoidal polarizing plate comprises a lamination of an optically anisotropic layer, a transparent substrate and a polarizing membrane. The optically anisotropic layer contains discotic compounds. The transparent substrate is optically anisotropic. The polarizing membrane is arranged as an outermost layer of the liquid crystal display. The optically anisotropic layer and the transparent substrate are so arranged that an angle between a normal discotic direction and a slow axis in plane of the transparent substrate is essentially 45.degree.. The normal discotic direction is an average of directions obtained by projecting normal lines of discotic planes of the discotic compounds on plane of the substrate. The transparent substrate and the polarizing membrane are so arranged that a slow axis in plane of the transparent substrate is essentially parallel to or essentially perpendicular to a transmission axis in plane of the polarizing membrane.
