Title:
LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/074392
Kind Code:
A1
Abstract:
Provided is a liquid crystal alignment agent capable of: forming a liquid crystal alignment film having a high voltage holding ratio; suppressing image lags caused by a long-term alternating current driving; and rapidly reducing charges that accumulate in the liquid crystal cell as a result of liquid crystal driving. Also provided are a novel diamine and a polymer suitable for the liquid crystal alignment agent. The liquid crystal aligning agent includes at least one polymer selected from the group consisting of: a polyimide precursor obtained by using a diamine component including a diamine represented by formula (DA); and a polyimide which is an imidization product of said polyimide precursor. Formula (1) (The definitions of symbols are as stated in the specification.)
