<p>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 negatively large 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. The invention 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. The invention is a liquid crystal composition that that has negative dielectric anisotropy and includes a two-ring compound having a negatively large dielectric anisotropy and having at least three fluorines at the lateral positions, as a first component, a specific compound having a small viscosity, as a second component and a specific compound having a negatively large dielectric anisotropy, as a third component, and is a liquid crystal display device containing this composition.</p> |
