Optical compensatory sheet, process for preparation of the same and liquid crystal display

摘要

An optical compensatory sheet comprises a transparent support, an orientation layer and an optically anisotropic layer in order. The optically anisotropic layer contains an aligned and fixed discotic liquid crystal compound. The orientation layer has a function of aligning the discotic liquid crystal compound. The function of the orientation layer is activated by irradiating the layer with light from a single direction. The present specification also discloses a process for the preparation of the optical compensatory sheet and a liquid crystal display using the optical compensatory sheet.
