Title:
LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT MEMBRANE, AND LIQUID CRYSTAL DISPLAY ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/170841
Kind Code:
A1
Abstract:
The present invention provides a liquid crystal display element comprising a liquid crystal alignment membrane capable of being fired at a low temperature and having good printability of a liquid crystal alignment agent (solubility of a polymer in a solvent), as well as good liquid crystal alignment and a good voltage retention rate, and also provides a liquid crystal alignment agent for forming said liquid crystal alignment membrane. The present invention relates to a liquid crystal alignment agent containing a polymer obtained by reacting at least one hydrazide derivative selected from the group consisting of formulas (1)-(3) with at least one compound selected from formulas (4) and (5) (in the formulas, W, X, and Z each independently represent a bivalent organic group, and Z represents a single bond or a bivalent organic group).
