Abstract: A liquid crystal aligning agent which contains a polymer (A) and a polymer (B). Polymer (A): A polymer which has at least one structural unit U1 selected from the group consisting of structural units represented by formula (1) and structural units represented by formula (2), and a structural unit U2 derived from at least one monomer selected from the group consisting of styrene monomers and (meth)acrylic monomers. Polymer (B): At least one polymer selected from the group consisting of polyamic acids, polyamic acid esters and polyimides. In the formulae, R7 represents a monovalent organic group having one or more carbon atoms; R8 represents a monovalent organic group having one or more carbon atoms; and R9 represents a hydrogen atom or a monovalent organic group having one or more carbon atoms.
