1. A liquid crystal alignment agent for photo-alignment, the liquid crystal alignment agent containing (A) a resin having a side chain including a structure of Formula (1) below, and (B) a compound of Formula (2) below,
in Formula (1), X1 is a benzene ring which may be substituted with a substituent, wherein the substituent is one or more of an alkyl group, a haloalkyl group, an alkoxy group, a halogen atom, a cyano group and a nitro group, and R is a substituent selected from OH and NH2;
in Formula (2), any 3-5 of R1, R2, R3, R4 and R5 are each independently a substituent selected from a hydrogen atom, a halogen atom, C1-6 alkyl, C1-6 haloalkyl, C3-8 cycloalkyl, C3-8 halocycloalkyl, C2-6 alkenyl, C2-6 haloalkenyl, C3-8 cycloalkenyl, C3-8 halocycloalkenyl, C2-6 alkynyl, C2-6 haloalkynyl, C1-6 alkoxy, C1-6 haloalkoxy, (C1-6 alkyl)carbonyl, (C1-6 haloalkyl)carbonyl, (C1-6 alkoxy)carbonyl, (C1-6 haloalkoxy)carbonyl, (C1-6 alkyl)aminocarbonyl, (C1-6 haloalkyl)aminocarbonyl, di(C1-6 alkyl)aminocarbonyl, cyano and nitro, and when any 3 or 4 of R1, R2, R3, R4 and R5 are as defined above, the remaining one or two of R1, R2, R3, R4 and R5 is/are a group of Formula (3) below,
in Formula (3), the dashed line is a bond, R6 is C1-30 alkylene, phenylene, or a divalent carbocyclic ring or heterocyclic ring, one or a plurality of hydrogen atoms of the alkylene, phenylene, or divalent carbocyclic ring or heterocyclic ring is optionally substituted with a fluorine atom, and when R6 is C1-3 alkylene, CH2CH2 of R6 is optionally replaced by CH?CH, CH2 of R6 is optionally replaced by phenylene or a divalent carbocyclic ring or heterocyclic ring, and is optionally replaced by O, NHCO, CONH, COO, OCO, NH, NHCONH, or CO, provided these groups are not adjacent to each other, and R7 is a hydrogen atom or a methyl group, and n is an integer of 0 or 1.
