The present invention provides a liquid crystal composition having a high upper limit temperature in a nematic phase, a low minimum temperature of a nematic phase, a small viscosity, an appropriate optical anisotropy, a large negative dielectric anisotropy, and a large specific resistance. Among the characteristics such as high stability against ultraviolet light and high stability against heat, at least one characteristic is satisfied or an appropriate balance is provided between at least two characteristics. The present invention also provides an AM device which has characteristics such as short response time, large voltage holding ratio, low threshold voltage, large contrast ratio, and long life. The present invention is a liquid crystal composition containing a specific compound having high stability to ultraviolet rays as a first component, and having a negative dielectric anisotropy, and a liquid crystal display element containing the composition, and the composition may also have a large A specific compound having a negative dielectric anisotropy as a second component, a specific compound having a high upper limit temperature or a small viscosity as a third component and a specific compound having a polymerizable group as an additive component. |
