<p>Disclosed is a liquid crystal composition which satisfies at least one of such characteristics as a wide temperature range 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 light, 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 has a negative dielectric anisotropy, and contains, as a first component, a bicyclic compound having a large negative dielectric anisotropy, wherein a fluorine atom or a chlorine atom is in at least three lateral positions, and as a second component, a specific compound having a large negative dielectric anisotropy. The liquid crystal composition may additionally 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 display element contains the composition.</p> |
