<p>Disclosed is a liquid crystal composition which satisfies at least one of such characteristics as high upper limit temperature of the nematic phase, low lower limit temperature of the nematic phase, low viscosity, adequate optical anisotropy, large negative dielectric anisotropy, high resistivity, high stability with respect to ultraviolet light and high stability with respect to heat, or which has an adequate balance between at least two of the above-mentioned characteristics. Also disclosed is an AM element having a short response time, high voltage holding ratio, high contrast ratio, long life and the like. The liquid crystal composition contains a specific compound having a large negative dielectric anisotropy as a first component, and a specific compound containing a pyran ring and having a large negative dielectric anisotropy as a second component. The liquid crystal composition may also contain a specific compound having a low viscosity as a third component, and a specific compound having a large negative dielectric anisotropy as a fourth component. The liquid crystal composition has a negative dielectric anisotropy. The liquid crystal display element contains the composition.</p> |
