Title:
LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/070515
Kind Code:
A1
Abstract:
A polymer (A) having structural units derived from at least one monomer selected from the group consisting of a compound represented by formula (1) and a compound represented by formula (2) is included in this liquid crystal alignment agent. In the formulas, of R1 and R2, one of R1 and R2 is a univalent group having a polymerizable group and the other is a hydrogen atom or a univalent organic group, or R1 and R2 are combined with each other to represent a ring structure formed along with the nitrogen atom to which R1 and R2 are bonded. However, the ring structure has a polymerizable carbon-carbon unsaturated bond. In the formulas, A1 is a univalent organic group, and A2 is a hydroxyl group or a univalent organic group. In the formulas, 0 ≤ n1 + n2 ≤ 8 is satisfied.
