ABSTRACT:
A liquid crystal display of transmission type comprises a light source, a polarizing film, a liquid crystal cell and another polarizing film in this order. An optical compensatory sheet is further provided between the liquid crystal cell and the polarizing film on a light source side or between the liquid crystal cell and the polarizing film on a display side. The optical compensatory sheet comprises a transparent support and an optically anisotropic layer. The optically anisotropic layer contains a discotic compound having a discotic plane. The discotic plane is inclined from a surface of the support surface at an angle. The angle varies along a direction of depth of the optically anisotropic layer. The liquid crystal display has a difference in chromaticity (ΔCuv) of 0.05 or less. The difference is measured between an image seen frontally and an image seen rightward or leftward at a viewing angle of 60°.
