In the high upper limit temperature, a low lower limit temperature of the nematic, a small viscosity, a suitable optical anisotropy, parts of large dielectric anisotropy, a large specific resistance, a high stability, characteristics such as high stability to heat of the ultraviolet rays on the nematic, the at least one of the characteristics provides a liquid crystal composition having a suitable balance with respect to the, or at least two characteristics are met. Provides a AM device having a short response time, a large voltage holding ratio, a large contrast ratio, a long service life and so on.
The specific three ring compound having a large optical anisotropy as a first component, and a specific compound having a small viscosity as a second containing larger compounds dielectric anisotropy this portion having a methylene oxy group or pyran ring as a second component, and a third component, and and it may contain a specific compound having a large dielectric anisotropy as a fourth component part, respectively, and the liquid crystal display element containing the liquid crystal composition, and the composition having a negative dielectric anisotropy.
