To provide a liquid crystal composition satisfying at least one of characteristics such as high maximum temperature of a nematic phase, low minimum temperature of the nematic phase, small viscosity, suitable optical anisotropy, large dielectric anisotropy, large specific resistance, high stability to ultraviolet light and heat, or to provide a liquid crystal composition having a suitable balance regarding at least two of the characteristics; and to provide 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 contains a specific compound having high maximum temperature or large positive dielectric anisotropy as a first component and a specific compound having large negative dielectric anisotropy and low minimum temperature as a second component, and may contain a specific compound having small viscosity or large maximum temperature as a third component. A liquid crystal display device includes the composition having positive dielectric anisotropy. |
