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 Rand Rindependently represents a hydrogen atom, a halogen atom or a monovalent organic group having one or more carbon atoms; and each of Xand Xindependently represents &#x2014;OH, &#x2014;NHor a monovalent organic group having one or more carbon atoms, provided that at least one of Xand Xrepresents '&#x2014;OR' or '&#x2014;NRR' (wherein each of Rand Rindependently represents a hydrogen atom or a monovalent organic group having one or more carbon atoms).

Liquid crystal aligning agent, liquid crystal alignment film, liquid crystal element and polymer

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.
