This liquid crystal aligning agent contains: a polyimide precursor which is obtained from a diamine component containing a diamine having a structure represented by formula (1) and a diamine having a prescribed side chain structure; and/or a polyimide polymer that is an imidation product of said polyimide precursor. (In formula (1), A1 and A5 each independently denote a single bond or an alkylene group having 1-5 carbon atoms. A2 and A4 each independently denote an alkylene group having 1-5 carbon atoms. A3 denotes an alkylene group having 1-6 carbon atoms or a cycloalkylene group. B1 and B2 each independently denote a single bond, -O-, -NH-, -N(CH3)-, -CO-, -COO-, -OCO-, -CONH-, -NHCO-, -CON(CH3)- or -N(CH3)CO-. D1 denotes a protecting group. a is 0 or 1. * denotes the site of bonding to another group).
