To provide a liquid crystal composition satisfying at least one of characteristics such as a high maximum temperature of a nematic phase, a low minimum temperature of the nematic phase, small viscosity, suitable optical anisotropy, large dielectric anisotropy, large specific resistance, high stability to ultraviolet light, high stability to heat and a large elastic constant, or is to provide a liquid crystal composition having a suitable balance regarding at least two of the characteristics; an AM device having short response time, a large voltage holding ratio, a large contrast ratio, a long service life and so forth. The liquid crystal composition has the nematic phase and contains a compound having a difluoromethyleneoxy group and a trifluoromethyl group and having large dielectric anisotropy as a first component, and a specific compound having small dielectric anisotropy as a second component. The liquid crystal display device contains the composition. |
