Title:
LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT, AND DIAMINE AND PRODUCTION METHOD THEREFOR, AND POLYMER
Document Type and Number:
WIPO Patent Application WO/2020/054797
Kind Code:
A1
Abstract:
This liquid crystal alignment agent contains at least one polymer selected from polyimide precursors including a structural unit represented by formula [3-1], and polyimides that are imide compounds of the polyimide precursors. In the formula, V0 represents a tetravalent organic group derived from a tetracarboxylic acid derivative, W1 represents a divalent organic group represented by formula [2-1], and R3 and R4 each independently represent a hydrogen atom or an alkyl group having 1-5 carbon atoms. In the formula, Y1 represents a tetravalent organic group having an alicyclic structure, X1 and X2 each represent a divalent organic group, Z1 and Z2 each independently represent a single bond, -NH-, or -O-, R1 and R2 each independently represent an alkyl group having 1-5 carbon atoms, and * represents a bonding site.
