| 摘要 |
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 positive 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 has a positive dielectric anisotropy, and contains: a specific tetracyclic compound having a high upper limit temperature of the nematic phase and a large dielectric anisotropy, as a first component; a specific tetracyclic compound having a large positive dielectric anisotropy, as a second component; and a specific tetracyclic compound having a high upper limit temperature of the nematic phase, as a third component. Also disclosed is a liquid crystal display element containing the composition. |
