To provide a liquid crystal composition satisfying at least one characteristic 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, or has a suitable balance regarding at least two characteristics. To provide an AM device having short response time, a large voltage holding ratio, a large contrast ratio, long service life and so forth. A liquid crystal composition has a nematic phase and contains a specific compound having large dielectric anisotropy as a first component and a specific compound having small viscosity as a second component, and may contain a specific compound having high maximum temperature or small viscosity as a third component and a specific compound having large dielectric anisotropy as a fourth component, and a liquid crystal display device includes the composition.
