摘要

本发明提供一种液晶配向剂其均匀涂布性优异，并可制作可高速回应且电压保持率、残影特性以及耐光性优异的液晶显示元件。该液晶配向剂，系含有[A]选自包含聚醯胺酸、聚醯亚胺、(甲基)丙烯酸聚合物、聚矽氧烷及聚醯胺酸酯之群组中的至少1种聚合物，且该聚合物具有以下述式(1)表示的基团，其中R 3 较佳为以下述式(2)表示的基团。;The present invention is providing a liquid crystal alignment agent, which could prepare a liquid crystal display element capable of fast response with superior voltage retention rate, afterimage characteristics and light resistance, and excellent in coating uniformity. The liquid crystal alignment agent contains polymer [A], which is at least one selected from a group including polyamic acid, polyimide, methacrylic polymer, polysiloxane and polyamic acid ester. Furthermore, the polymer is having a group represented by the following formula (1), wherein R 3 is preferred a group represented by the following formula (2).
