摘要:
An optical compensatory sheet is composed of a transparent support, an orientation layer and an optically anisotropic layer. The orientation layer is a crosslinked polymer layer a surface of which has been subjected to rubbing treatment, and the optically anisotropic layer is made of a discotic liquid crystalline compound. A liquid crystal display is composed of a liquid crystal cell, a polarizing sheet arranged on each side of the cell, and the optical compensatory sheet provided between at least one side of the liquid crystal cell and the polarizing sheet. A color liquid crystal display has also the optical compensatory sheet.
