A liquid crystal alignment film capable of achieving both a wide viewing angle characteristic and high-quality display and a good afterimage characteristic and image sticking characteristic, or a boundary between adjacent regions in which the polarization state is stably maintained and the polarization state is different A liquid crystal aligning agent capable of forming a liquid crystal alignment film for producing a retardation film having excellent contrast with a photo-alignment method. The liquid crystal aligning agent has the following formula (1): (In the formula (1), R is an alkyl group having 1 to 4 carbon atoms, a hydroxyl group, a halogen atom or a cyano group, a is an integer of 0 to 4, and “*” is a bond. Represents that.) The polymer which has a structure represented by these is contained. [Selection figure] None |
