Document Type and Number:
WIPO Patent Application WO/2022/107545
Kind Code:
A1
Abstract:
A liquid crystal aligning agent which contains at least one polymer (A) that is selected from the group consisting of polyimide precursors having a repeating unit (a1) represented by formula (1) and polyimides that are imidized products of the polyimide precursors. (At least one of R1 to R4 represents a group other than a hydrogen atom, for example an alkyl group having from 1 to 6 carbon atoms.) (Each of Ra1 to Ra3 represents, for example, a monovalent organic group having from 1 to 3 carbon atoms; L1 represents, for example, *1-O-C(=O)-*2; L2 represents, for example, *2-C(=O)-O-*3; and a1 to a3 satisfy (a1 + a2 + a3) ≥ 1.)
