Optical compensatory sheet comprising substrate, orientation layer and optically anisotropic layer |
摘要 |
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 denatured polyvinyl alcohol having a hydrocarbon group containing 10 to 100 carbon atoms or a denatured polyvinyl alcohol containing fluorine atoms. The discotic liquid crystal molecules are aligned at an average inclined angle in the range of 50° to 90°. An orientation layer, a liquid crystal display of an STN mode and a method of alignment of discotic liquid crystal molecules are also disclosed.
