Title:
LIQUID CRYSTAL ALIGNING AGENT, LIQUID CRYSTAL ALIGNMENT FILM AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/181818
Kind Code:
A1
Abstract:
A liquid crystal aligning agent which contains a polymer that is obtained from a diamine having a structure represented by formula (1). In the formula, R represents a hydrogen atom or a monovalent organic group; R1 represents a hydrogen atom or a linear or branched alkyl group or aryl group having 1-5 carbon atoms; two R1 moieties on a same maleimide ring may be the same as or different from each other, and the two R1 moieties may combine with each other to form an alkylene group having 3-6 carbon atoms; W1 represents a single bond or a divalent organic group; W2 represents a divalent organic group; Ar1 represents an aromatic ring; and L1 represents a single bond, a carbonyl group, a sulfonyl group or an alkylene group having 1-20 carbon atoms.
