Abstract
A liquid crystal display element having pretilt angles and anchoring energies with respect to liquid crystal molecules that differ between a pair of opposed substrates, a liquid crystal display element having pretilt angles and anchoring energies with respect to liquid crystal molecules that vary at a same substrate, and an optically anisotropic film having a plurality of optically different regions is provided. Thus, a liquid crystal display element that has improved display characteristics, response, and the like can be obtained. Methods of producing such liquid crystal display elements and such an optically anisotropic film are provided. The production methods are simply carried out utilizing the irradiation of polarized light. Thus, the present invention is of great value to industry.
