The purpose of the present invention is to provide a liquid crystal aligning agent having excellent applicability (printability) even when using a general purpose solvent as a relatively low pre-tilt angle is manifested by a light aligning method. A liquid crystal aligning agent contains at least one type of a polymer (but the polymer has a residue of a bivalent group indicated as a formula (1) shown below) selected from a group composed of polyorganosiloxane, polyamide, poly(thio)ester, and (meta) acrylic acid copolymer. (The formula (1), RI-RIV are independently a hydrogen atom, a halogen atom, an alkyl group of 1-12 of carbon number or an alkenyl group of 2-12 of carbon number; Y1 and Y2 are independently an organic residue of the bivalent group, and ″*″ separately indicates a combination damage combined with a polymer chain.).
