Optical compensatory sheet comprising substrate and optically anisotropic layer

摘要

An optical compensatory sheet comprises a transparent substrate and an optically anisotropic layer. The optically anisotropic layer comprises discotic liquid crystal molecules. The discotic liquid crystal molecules are oriented in essentially mono domain alignment at an average inclined angle in the range of 50° to 90°. A liquid crystal display of an STN mode having the optical compensatory sheet is also disclosed.
