| description | Provided is a liquid crystal aligning agent in which there is little occurrence of after-images derived from residual DC voltage and AC after-images, which can be easily reworked and which can form a liquid crystal alignment film having high transmittance. This liquid crystal alignment agent is characterized by containing a component (A) and a component (B). Component (A): A polymer (A) having a repeating unit represented by formula (1). Component (B): A polymer (B) having a repeating unit represented by formula (2) and a repeating unit represented by formula (3). (X1 is a tetravalent organic group; Y1 is a divalent organic group; X2 and X3 are each a tetravalent organic group derived from a tetravalent alicyclic tetracarboxylic acid dianhydride or alicyclic aliphatic tetracarboxylic acid dianhydride; R2 is a hydrogen atom or the like; Z21, Z22, Z31 and Z32 are hydrogen atoms or the like; Y3 is a divalent organic group having a partial structure represented by formula (n); R3 is a hydrogen atom or the like; Q |
