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, a large elastic constant, high stability to ultraviolet light and heat, or having a suitable balance regarding at least two of the characteristics; and an AM device having characteristics such as short response time, a large voltage holding ratio, a large contrast ratio or a long service life. The liquid crystal composition has the nematic phase and contains a specific compound having large positive dielectric anisotropy as a first component, 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, a specific compound having large positive dielectric anisotropy as a fourth component or a specific compound having negative dielectric anisotropy as a fifth component, and a liquid crystal display device includes the composition. |
