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