Title:
LIQUID CRYSTAL ALIGNMENT AGENT AND PREPARATION METHOD THEREFOR, LIQUID CRYSTAL ALIGNMENT FILM AND PREPARATION METHOD THEREFOR, AND LIQUID CRYSTAL CELL
Document Type and Number:
WIPO Patent Application WO/2022/095722
Kind Code:
A1
Abstract:
The present invention relates to the field of liquid crystal alignment agents, and provides a liquid crystal alignment agent and a preparation method therefor, a liquid crystal alignment film and a preparation method therefor, and a liquid crystal cell. In the present invention, a piperazine monomer is added into the liquid crystal alignment agent, so that the bulk resistance value and the surface resistance value of a liquid crystal alignment agent material can be decreased, the residual charge release capability of the alignment agent material is effectively improved, and the reliability and stability of an electronic product are further improved. The liquid crystal cell using the liquid crystal alignment agent of the present invention has the advantages of high voltage holding ratio, low residual voltage, and the like.
