Document Type and Number:
WIPO Patent Application WO/2015/152174
Kind Code:
A1
Abstract:
Provided is a liquid crystal alignment film that exhibits both satisfactory flatness and excellent afterimage characteristics. A liquid crystal alignment agent that contains component (A) and component (B). Component (A): a copolymer that has a structural unit represented by formula (1) and a structural unit represented by formula (2). Component (B): at least one polymer selected from the group consisting of polyimide precursors that have a structural unit represented by formula (3) and imidized polymers of the polyimide precursors. (X1, X2, and X3 each represent a tetravalent organic group, Y1, Y2, and Y3 each represent a bivalent organic group, R1 represents a C1-5 alkyl group, R2 represents a hydrogen atom or a C1-5 alkyl group, and A1, A2, Z1, and Z2 each represent a hydrogen atom or a C1-10 alkyl group that may have a substituent, a C2-10 alkenyl group that may have a substituent, or a C2-10 alkynyl group that may have a substituent.)
