The properties such as high upper temperature of nematic phase, low lower temperature on nematic phase, small viscosity, appropriate optical anisotropy, large dielectric anisotropy, high specific resistance, high stability against ultraviolet rays, , A liquid crystal composition is provided which satisfies at least one characteristic or has an appropriate balance with respect to at least two characteristics. A short response time, a large voltage holding ratio, a low threshold voltage, a large contrast ratio, a long lifetime, and the like. A liquid crystal composition containing a compound that contributes to high stability to heat or ultraviolet rays, has a negative dielectric anisotropy, and has a nematic phase. The composition is a specific compound having a negative dielectric anisotropy as a first component, The composition may contain a specific compound having a high upper limit temperature or a small viscosity. |
