Abstract: A composition includes a compound including a partial structure represented by formula (1), and solvent. In the formula (1), X1 and X2 each independently represent a substituted or unsubstituted ring structure having 4 to 10 ring atoms constituted taken together with the spiro carbon atom and the carbon atoms of the aromatic ring adjacent to X1 or X2; n1 and n2 are each independently an integer of 0 to 2; and the sum of k1 and k2 are each independently an integer of 1 to 8, wherein the sum of k1 and k2 is no less than 2 and no greater than 16. The compound is preferably represented by formula (2). The sum of k1 and k2 in the formula (1) is preferably no less than 3.

Abstract: Provided is a liquid crystal alignment agent that makes it possible to obtain a liquid crystal alignment film having a superior balance among solvent resistance, liquid crystal alignment properties, and voltage holding ratio. The liquid crystal alignment agent contains a polymer [P] including: at least one ring structure of an oxetane ring and an oxirane ring; (B) a functional group that reacts with at least one of the oxetane ring and the oxirane ring by heating; and (C) an optically aligning group.

Abstract: According to the present invention, a liquid crystal aligning agent is configured to contain a polymer [P] which has a partial structure represented by formula (1) and comprises a photo-alignment group. In formula (1), each of R1 and R2 independently represents a hydrogen atom, a halogen atom or a monovalent organic group having one or more carbon atoms; and each of X1 and X2 independently represents —OH, —NH2 or a monovalent organic group having one or more carbon atoms, provided that at least one of X1 and X2 represents “—OR3” or “—NR3R4” (wherein each of R3 and R4 independently represents a hydrogen atom or a monovalent organic group having one or more carbon atoms).
