Providing a liquid crystal composition satisfies at least one of characteristics like high maximum temperature of a nematic phase, low minimum temperature of the nematic phase, small viscosity, suitable optical anisotropy, large negative dielectric anisotropy, large specific resistance, high stability to ultraviolet light and high stability to heat or has a suitable balance regarding at least two of the characteristics. Providing an AM device has a short response time, a large voltage holding ratio, a large contrast ratio, a long service life and so forth. The liquid crystal composition has a negative dielectric anisotropy and contains a specific compound having large negative dielectric anisotropy as a first component, a specific two-ring compound having low minimum temperature and negative dielectric anisotropy as a second component and a specific two-ring compound having low viscosity as a third component. The liquid crystal display device contains the composition.
