The subject is to provide liquid crystal display device that has characteristics such as a short response time, a large voltage holding ratio, a low threshold voltage, a large contrast ratio, a long service life and a small flicker rate.
Means for solution
The invention relates to a liquid crystal display device having an electrode group formed on one or both of a pair of substrates that are opposed to each other, and a plurality of active devices connected to the electrode group, and a liquid crystal alignment film formed on the opposing surfaces of the pair of substrates, and a liquid crystal composition sandwiched in between the pair of substrates, wherein the liquid crystal alignment film includes a polymer having a photodegradable group, and the liquid crystal composition includes at least one compound represented by formula (1) as a first component:
in formula (1), R1 and R2 are independently alkyl having 1 to 12 carbons or the like; ring A and ring C are independently 1,4-cyclohexylene or the like; ring B is 2,3-difluoro-1,4-phenylene or the like; Z1 and Z2 are independently a single bond or the like; a is 0, 1, 2 or 3; b is 0 or 1; and the sum of a and b is 3 or less.
本课题旨在提供具有响应时间短、电压保持比大、阈值电压低、对比度大、使用寿命长和闪烁率小等特性的液晶显示装置。
解决方法
本发明涉及一种液晶显示装置,该装置具有形成在一对彼此相对的基板中的一个或两个上的电极组,以及连接到电极组的多个有源器件,和形成在这对基板的相对表面上的液晶排列膜,以及夹在这对基板之间的液晶组合物,其中液晶排列膜包括具有光降解基团的聚合物,而液晶组合物包括至少一种由式(1)表示的化合物作为第一组分:
在式 (1) 中,R1 和 R2 独立地为具有 1 至 12 个碳原子的烷基或类似物;环 A 和环 C 独立地为 1,4-环己烯或类似物;环 B 为 2,3-二氟-1,4-亚苯基或类似物;Z1 和 Z2 独立地为单键或类似物;a 为 0、1、2 或 3;b 为 0 或 1;a 和 b 之和为 3 或更少。
