Document Type and Number:
WIPO Patent Application WO/2017/065226
Kind Code:
A1
Abstract:
The present invention provides: a liquid crystal alignment agent that makes it possible to obtain a liquid crystal alignment film that has excellent rubbing resistance, fast reduction of accumulated charge and a high alignment regulating force; a liquid crystal display element, particularly of the transverse electric field type, that has excellent display properties; and a novel diamine that constitutes the raw material of the liquid crystal alignment agent. The liquid crystal alignment agent contains a polymer that has a structure represented by formula (1) in the main chain. (R1 is hydrogen or a monovalent organic group, Ar is a phenyl group or naphthalene group that can have a substituent group, and * represents a site that bonds with another group.)
