Abstract:
A photo-alignment polymer has a repeating unit represented by Formula (1), in Formula (1), R1 represents a hydrogen atom or a substituent, X represents —O—, —S—, or —NR2—, in which R2 represents a hydrogen atom or a substituent, L1 represents a single bond or a divalent linking group, P represents a photo-aligned group, and A represents an acid-cleavage group which is decomposed by an action of acid to produce a polar group
