ABSTRACT:
A liquid crystal display comprises a liquid crystal cell of a vertical alignment mode, one or two optical compensatory sheets arranged on one or both sides of the liquid crystal cell and two polarizing elements arranged on the optical compensatory sheets or the liquid crystal cell. The liquid crystal cell contains a liquid crystal molecule. The liquid crystal molecule is essentially vertically aligned while not applying voltage to the cell, and is essentially horizontally aligned while applying voltage to the cell. The optical compensatory sheet comprises a transparent substrate and an optically anisotropic layer. The optically anisotropic layer contains a discotic compound. The optically anisotropic layer has an optical anisotropy to optically compensate an optical anisotropy of the liquid crystal cell while applying voltage to the cell. The optical compensatory sheet has a retardation value in plane in the range of -10 to 10 nm.
