液晶取向剂和液晶显示元件
摘要：
提供在使聚酰亚胺类液晶取向膜维持电压保持率的同时又使其减少蓄积电荷、并且具有优良的印刷性的液晶取向剂，以及采用它的液晶显示元件。所述液晶取向剂是含有上述式(1)表示的化合物的聚酰亚胺类液晶取向剂。(式中，2个R1各自独立地为氢、烷基、烷氧基或氨基，Y为－S－、－NH－、－O－、－CH2－或单键中的任意一种，X1和X2各自独立地为上述式(2)结构中的任意一种)。(式中，Z1、Z2和Z3各自独立地为氢、烷基、烷氧基、氨基或二缩水甘油基氨基)。
摘要（英）：

Provided is liquid crystal oriented agent which causes a polyimide liquid crystal oriented film to maintain the voltage retention percentage and reduce cumulated charges, with excellent printing properties and a liquid crystal element thereof. The liquid crystal oriented agent is the polyimide liquid crystal oriented agent containing the compound by the formula (1), wherein two R1s are respectively hydrogen, alkyl, alkoxyl group, or amido, Y is -S-, -NH-, -O-, -CH2 any one in a single bond, X1 and X2 are respectively any in the structure of formula (2). Z1, Z2 and Z3 are respectively hydrogen, alkyl, alkoxyl group or amido or 2-glycidyl group amido.
