(57) [Problem] When a liquid crystal alignment film is used, a liquid crystal alignment film having good vertical alignment of liquid crystal, high voltage holding characteristics, low residual DC, and excellent printability can be formed. To provide a vertical liquid crystal aligning agent. (A) The following formula (1): Wherein R 1 is a halogen atom, an alkyl group having 1 to 10 carbon atoms or a fluoroalkyl group having 1 to 10 carbon atoms, and a is an integer of 0 to 4; (B) Formula (2) below Here, X is a divalent organic group, and R 2 has 4 to 4 carbon atoms. Is a divalent organic group having an alicyclic skeleton of 0, at least one of a polyamic acid produced by reacting with a diamine represented by the formula (I) and an imidized polymer produced by subjecting the polyamic acid to dehydration and ring closure. Liquid crystal alignment agent contained. |
