| titleOfInvention | Liquid crystal alignment agent, liquid crystal alignment film, and liquid crystal display element |
| abstract | The present invention provides: a liquid crystal alignment agent which makes it possible to obtain a liquid crystal alignment film in which there is little variation of liquid crystal twist angles, in which an AC afterimage can be suppressed, and in which substrate separation is unlikely to occur; a liquid crystal alignment film; and a liquid crystal display element. The liquid crystal alignment agent contains component (A) and component (B). Component (A): A polyamic acid ester (A) which has two or more types of a structural unit (a-1Da) represented by formula (1Da) and a structural unit (a-1Ta) represented by formula (1Ta). Component (B): A polyamic acid (B) which has a structural unit (b-1Tb) represented by formula (1Tb) and a structural unit (b-1Db) represented by formula (1Db). (R 11 to R 14 represent a hydrogen atom, a C1-C6 alkyl group, or the like, and at least one of R 11 to R 14 represents a group other than a hydrogen atom. The two R 1 represent a hydrogen atom or a t-alkyl group, where at least one of the two represents a t-alkyl group. Y 1 is a divalent organic group represented by formula (H 1 ). Z represents a hydrogen atom or the like.) (Ar 1 and Ar 1' represent a benzene ring or the like. A represents a C1-C10 divalent organic group having an alkylene structure. L 1 and L 1' represent a single bond or the like.) (X b represents a tetravalent organic group, Y b represents a divalent organic group, and Z represents a hydrogen atom or the like.) |
