Abstract
A method of aligning liquid crystals is disclosed. The method includes forming an optically active compound-containing polymeric film to be used as an aligning layer on a surface of each of a lower substrate and an upper substrate; irradiating circularly polarized light on the polymeric film to obliquely align the optically active compound contained relative to the substrate surface to form the aligning layer; positioning the lower substrate and the upper substrate in opposite to each other such that the polymeric film on the lower substrate is opposite to the polymeric film on the upper substrate; and pouring a liquid crystal between the substrates, thereby to obliquely align molecules of the liquid crystal due to the optically active compound aligned.
