Abstract
An optical compensatory sheet comprises a transparent substrate, an orientation layer and an optically anisotropic layer in order. The optically anisotropic layer comprises discotic liquid crystal molecules. The orientation layer comprises a polymer having a hydrocarbon side chain containing 10 or more carbon atoms or a fluoropolymer. The discotic liquid crystal molecules are aligned at an average inclined angle in the range of 50° to 90°. A liquid crystal display of an STN mode and a method of alignment of discotic liquid crystal molecules are also disclosed.
