Disclosed is a liquid crystal alignment film which has a satisfactory level of solvent resistance and in which the reduction in a voltage holding ratio can be prevented even when exposed to irradiation with light. The liquid crystal alignment film is produced using a diamine compound represented by formula [2]. In the formula, X1 represents -O-, -NH-, -N(CH3)-, -CONH-, -NHCO-, -CH2O-, -COO-, -OCO-, -CON(CH3)- or N(CH3)CO-; X2 represents an alkylene group having 1 to 5 carbon atoms; X3 represents a structure represented by formula [1a]; and n represents an integer of 1 to 4. |
