<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, large optical anisotropy, large dielectric anisotropy, high resistivity, high elastic constant, 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 which has a short response time, high voltage holding ratio, high contrast ratio, long life and the like. The liquid crystal composition has a nematic phase and contains a specific bicyclic compound having a high upper limit temperature, a low viscosity and a high elastic constant as a first component, and a specific compound having a high upper limit temperature and a large dielectric anisotropy as a second component. The liquid crystal display element contains the composition.</p> |
