摘要:
The invention is to provide a liquid crystal composition that satisfies at least one of characteristics such as a high maximum temperature of a nematic phase, a low minimum temperature of a nematic phase, a small viscosity, a suitable optical anisotropy, a large negative dielectric anisotropy, a large specific resistance, a high stability to ultraviolet light and a high stability to heat, or that is suitably balanced regarding at least two of the characteristics; and is to provide a AM device that has a short response time, a large voltage holding ratio, a large contrast ratio, a long service life and so forth, wherein the liquid crystal composition has negative dielectric anisotropy and includes a two-ring compound having a large negative dielectric anisotropy and having at least three fluorines or chlorines at the lateral positions as a first component, a specific compound having a large negative dielectric anisotropy as a second component, a specific compound having a small viscosity as a third component, and a specific compound having a large negative dielectric anisotropy as a fourth component, and the liquid crystal display device contains this composition.
