Document Type and Number:
Japanese Patent JP6561514
Kind Code:
B2
Abstract:
The invention relates to a liquid crystal aligning agent, a liquid crystal aligning film and a liquid crystal display element. The subject of the invention is end capped polyamide acid or liquid crystal aligning agent for optical aligning film of the derivative of the end capped polyamide acid which is obtained by reaction of Tetracarboxylic acid dianhydride, diamine compounds and amino silane compounds. The liquid crystal display element for a liquid crystal aligning film formed through the liquid crystal aligning agent for the optical aligning film can control generation of the foreign matter in the liquid crystal layer in the element to maintain orientation, aligning stableness, contrast, AC after image and other characteristics.
