<p>The invention provides 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 between at least two of the characteristics. The invention provides an AM device that has a short response time, a large voltage holding ratio, a large contrast ratio, a long service life and so forth. Herein, the liquid crystal composition has negative dielectric anisotropy and includes a specific two-ring compound having a low minimum temperature as a first component and a specific compound having a large negative dielectric anisotropy as a second component, and may include 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.</p> |
