摘要

本发明提供一种液晶配向剂，其可形成历经长期而电压保持率的下降少、可靠性优异的液晶配向膜。液晶配向剂含有具有式(1)所表示的结构的聚合物。;* -X 1 -(CR 1 2)m1-Y-(CR 1 2)m2-X 2 - * (1);式(1)中，X 1 及X 2 为单键、氧原子、硫原子、羰基或酯键，X 1 及X 2 两者不会同时为单键，Y是自5员环或6员环的杂芳香族化合物中去除2个氢原子而获得的基团，杂芳香族化合物在环结构中包含1个或2个选自由氮原子、氧原子及硫原子所组成的组群中的1种以上杂原子，存在多个的R 1 为氢原子或氟原子，m1及m2为0~20的整数，且「*」分别表示结合键。;* -X 1 -(CR 1 2)m1-Y-(CR 1 2)m2-X 2 - * (1) ;In formula (1), X 1 and X 2 each represent a single bond, an oxygen atom, a sulfur atom, a carbonyl group, or an ester bond, wherein X 1 and X 2 are not a single bond at the same time; Y is a group obtained by removing two hydrogen atoms from a heterocyclic aromatic compound containing a 5-membered ring or a 6-membered ring, and the heterocyclic aromatic compound contains in ring structure one or two of one or more kinds of heteroatom selected from a group consisting of a nitrogen atom, an oxygen atom, and a sulfur atom; a plurality of R 1 present in formula (1) are a hydrogen atom or a fluorine atom; m1 and m2 are integrals of 0 to 20; and “*”
