(OBJECTIVE) A liquid crystal aligning layer having a good bonding property with a substrate. (SOLUTION) Among the polymer components of a liquid crystal aligning agent, a repeating unit (a) having an optical aligning function, a repeating unit (b) having at least one kind selected from a group of at least five-membered heterocycles, cyclic ketone, and alkyl chain, and a repeating unit (c) having at least one kind selected from a group of oxetanyl radical and oxiranyl radical are included. |
