Title:
LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/205736
Kind Code:
A1
Abstract:
The present invention provides: a liquid crystal aligning agent that forms a liquid crystal alignment film that, while having a high refractive index, has high light transmittance because of a lack of coloring properties; and a liquid crystal alignment agent that, in addition to the properties noted above, has high homeotropic alignment. This liquid crystal alignment agent contains a component (A) and a component (B), described below. Component (A) is a polymer (A) of at least one type chosen from the group consisting of polyimide precursors and polyimides that are imidated forms of such polyimide precursors; and component (B) is a polymer (B) characterized in that the polymer includes a repeated unit structure represented by formula (1) and has at least one triazine ring terminal, at least part of this triazine ring terminal being blocked by an arylamino group that comprises a cross-linking group.
