Document Type and Number:
WIPO Patent Application WO/2012/091109
Kind Code:
A1
Abstract:
Provided is a liquid crystal aligning agent capable of obtaining a liquid crystal alignment film wherein burrs and cuts associated with rubbing do not easily occur and there is little reduction in a voltage holding ratio even after light irradiation for a long time. The liquid crystal aligning agent contains a component (A) and a component (B), listed below. Component (A): An amine compound having one primary amino group and a hydroxyl group in a molecule and wherein the primary amino group and the hydroxyl group are bonded to an aliphatic hydrocarbon group or a non-aromatic cyclic hydrocarbon group. Compound (B): At least one type of polymer selected from a group comprising a polyamide precursor and a polyamide.
