Provided is a liquid crystal alignment agent in which a low voltage maintenance ratio is degraded by light (ultraviolet light). The present invention relates to the liquid crystal alignment agent comprising (A) a polymer and (B) one or more compounds. The polymer comprises one or more polymers selected from a group comprising polyamic acid, an amide polymer, a polyamic acid ester, and polyorganosiloxane. One or more compounds are selected from a group comprising compounds of a lower formula (1) and a lower formula (2).
