Liquid crystal composition, and liquid crystal display element

Abstract

Provided is a liquid crystal composition containing a polymerizable compound, and exhibiting at least one property from among properties such as high upper limit temperature, low lower limit temperature, low viscosity, appropriate optical anisotropy, negatively high dielectric constant anisotropy, and high specific resistance. Also provided is an AM element exhibiting properties such as low burning ratio, short response time, low threshold voltage, large voltage retention rate, large contrast ratio, and long lifespan. A liquid crystal composition containing compound (1) and compound (2), and a liquid crystal display element containing said composition are provided by the invention. In the compounds, P1 and P2 represent polymerizable groups; rings A, B, C, and E represent a 1,4-cyclohexylene, a 1,4-phenylene and such; ring D represent a 2,3-difluoro-1,4-phenylene and such; Z1 and Z2 represent an alkylene and such; L1, Z3 and Z4 represent a single bond and such; R1 and R2 represent an alkyl and such; and q, r and s represent the number 1 and such.
本发明提供一种液晶组合物,其含有聚合性化合物,而且于高上限温度、低下限温度、小的粘度、适当的光学各向异性、负的大介电各向异性、大的比电阻等特性中,满足至少1种特性;而且提供一种主动矩阵(AM)元件,其具有小的残像率、短的响应时间、低的临限电压、大的电压保持率、大的对比度、长寿命之类的特性。本发明提供含有化合物(1)以及化合物(2)的液晶组合物、以及含有该组合物的液晶显示元件。其中,P1及P2为聚合性的基团;环A、环B、环C及环E为1,4-亚环己基、1,4-亚苯基等;环D为2,3-二氟-1,4-亚苯基等;Z1及Z2为亚烷基等;L1、Z3及Z4为单键等;R1及R2为烷基等;q、r及s为1等。
