The liquid crystal aligning agent contains a polymer component and an α, β-unsaturated compound having two or more partial structures represented by the formula (1) or the formula (2) in one molecule. However, in the formulas (1) and (2), X 1 is a carbonyl group or a sulfonyl group, and L 1 is a desorbing group desorbed by the reaction with the group of the polymer component. 2 is an oxygen atom or a sulfur atom, R 5 is a hydrogen atom or a monovalent organic group having 1 or more carbon atoms. |
