Title:
LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM AND METHOD FOR MANUFACTURING SAME, LIQUID CRYSTAL ELEMENT, POLYMER AND COMPOUND
Document Type and Number:
WIPO Patent Application WO/2018/186055
Kind Code:
A1
Abstract:
According to the present invention, when a liquid crystal alignment film is obtained by an optical alignment method, a liquid crystal element having an excellent AC afterimage characteristics and long-term heat resistance is achieved. This liquid crystal alignment agent contains a polymer (P) having at least one selected from the group consisting of a partial structure represented by formula (1) and a partial structure represented by formula (2). In the formula, X1 is a tetra-valent organic group having a cyclobutane ring structure and has at least one substituent at a ring portion of the cyclobutane ring, X2 a divalent organic group having a specific structure having at least any one among a chain hydrocarbon structure and a cycloaliphatic hydrocarbon structure, and R5 and R6 are each independently a hydrogen atom or a monovalent organic group having 1-6 carbon atoms.
