In a liquid crystal display device produced by forming an orientation controlling film on each surface of upper and lower substrates having an electrode, placing a liquid crystal composition between said substrates, and then sealing the periphery of the substrate, the response times, particularly those at low temperatures can be reduced by using, as the aforesaid liquid crystal composition, a liquid crystal composition which is obtained by adding a material having a glass transition temperature (Tg) of -90°C or lower to a liquid crystal material base and has a To of -82°C or lower.
在通过在具有电极的上下基板的每个表面上形成取向控制膜、在所述基板之间放置液晶组合物、然后密封基板外围而生产的液晶显示设备中,通过使用作为上述液晶组合物的液晶组合物,可以缩短响应时间,特别是在低温下的响应时间,该液晶组合物是通过在液晶材料基体中添加
玻璃化转变温度(Tg)为-90°C 或更低的材料而获得的,其 To 为-82°C 或更低。
