Abstract
The present invention provides a novel polymerizable liquid crystal composition which can be used as an optical material, display material or recording material. More particularly, the present invention provides an optically anisotropic film comprising a photopolymerization product of such a polymerizable liquid crystal composition having a high orientation state fixed therein which functions to control light and is suitable for the application in the field of optoelectronics, liquid crystal display, etc. The present invention further provides a process for the preparation of such an optically anisotropic film. Moreover, the present invention provides a liquid crystal device comprising the foregoing optically anisotropic film.
