Title:
POLYMER COMPOSITION, LIQUID CRYSTAL ALIGINING AGENT, LIQUID CRYSTAL ALIGNMENT FILM, LIQUID CRYSTAL DISPLAY ELEMENT, AND METHOD FOR PRODUCING LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/112092
Kind Code:
A1
Abstract:
Provided is a polymer composition from which a liquid crystal alignment film, with which a substrate is less likely to peel off, can be obtained, and a liquid crystal display element having high durability against an external pressure can be obtained. This polymer composition contains a polymer (P) having at least one structural unit selected from the group consisting of formulae (m-1) and (m-2), and an organic solvent. (R1 and R2 each independently represent a hydrogen atom, a fluorine atom, or an alkyl group having 1-3 carbon atoms. R represents a hydrogen atom or an alkyl group having 1-10 carbon atoms. Rs represents a hydrogen atom or an alkyl group having 1-3 carbon atoms. X represents: a group including an oxazoline ring structure; a group including a partial structure "-NRaRb" (where, Ra and Rb each independently represent a hydrogen atom, a C1-C10 monovalent hydrocarbon group, or protective group, and at least one among Ra and Rb represents a protective group); a group including an oxetane ring; a group including a cyclic carbonate group; a group including -SiRm(OR')m' (R and R' each independently represent a hydrogen atom, or an alkyl group having 1-5 carbon atoms, m and m' each represent an integer satisfying m+m'=3, and m' represents an integer of at least 1.); or a group including a benzene ring substituted with a methylol group.)
