Provided 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 dielectric anisotropy, high resistivity, high stability with respect to ultraviolet light and high stability with respect to heat, or which has an adequate balance among at least two of the above-mentioned characteristics. Also provided is an AM element which has a short response time, high voltage holding ratio, high contrast ratio, long service life and the like. A liquid crystal display element which contains a liquid crystal composition that has a positive dielectric anisotropy and contains a specific compound which has a high upper limit temperature or a large positive dielectric anisotropy as a first component and a specific compound which has a large negative dielectric anisotropy and a low lower limit temperature as a second component. This liquid crystal composition may also contain a specific compound which has a small viscosity or a high upper limit temperature as a third component. |
