| abstract |
A liquid crystal alignment agent comprising (A) a polymer and (B) a polymer. (A): having at least one structural unit U1 selected from the group consisting of the structural unit represented by formula (1) and the structural unit represented by formula (2), and derived from a styrene-based monomer And a polymer of at least one structural unit U2 of a single unit in the group consisting of (meth) acrylic single units. (B): At least one polymer selected from the group consisting of polyamic acid, polyamic acid ester, and polyimide. In the formula, R 7 is a monovalent organic group having 1 or more carbon atoms, R 8 is a monovalent organic group having 1 or more carbon atoms, and R 9 is a hydrogen atom or monovalent organic group having 1 or more carbon atoms. |
