液晶組成物および液晶表示素子
Document Type and Number:
Japanese Patent JP5343967
Kind Code:
B2
Abstract:
A liquid crystal composition is provided that satisfies at least one of the characteristics such as a high maximum temperature of a nematic phase, a low minimum temperature of a nematic phase, a small viscosity, a large optical anisotropy, a large dielectric anisotropy, a large specific resistance, a high stability to ultraviolet light and a high stability to heat, or is properly balanced regarding at least two characteristics. An AM device is provided that has a short response time, a large voltage holding ratio, a large contrast ratio, a long service life and so forth. The liquid crystal composition having a negative dielectric anisotropy contains a first component having especially negatively large dielectric anisotropy, a second component having a large negative dielectric anisotropy and a low minimum temperature, a third component having a high maximum temperature or a small viscosity. The liquid crystal display device contains the liquid crystal composition.
