Abstract
To provide a liquid crystal alignment film having a sufficient alignment-regulating power and high resistance against blue laser beam and having, at the same time, excellent adhesion, and an optical element using it. A liquid crystal alignment film obtainable by bonding, by chemisorption to a substrate, an alignment-regulating precursor which undergoes anisotropic decomposition by irradiation with polarized ultraviolet light, and irradiating the alignment-regulating precursor bonded to the substrate, with polarized ultraviolet light, to let it undergo anisotropic decomposition and exhibit an alignment-regulating power.
