Abstract
Provided are a liquid crystal composition satisfying at least one of characteristics such as high maximum temperature, low minimum temperature, small viscosity, suitable optical anisotropy, large negative dielectric anisotropy, large specific resistance, high stability to ultraviolet light and high stability to heat, or the liquid crystal composition having a suitable balance regarding at least two of the characteristics; and an AM device having characteristics such as a short response time, a large voltage holding ratio, low threshold voltage, a large contrast ratio and a long service life. The liquid crystal composition has negative dielectric anisotropy and contains a specific compound having large negative dielectric anisotropy as a first component, a specific compound having low minimum temperature as a second component, and a specific compound having small viscosity as a third component, and the composition may contain a specific compound having high maximum temperature or small viscosity as a fourth component, a specific compound having negative dielectric anisotropy as a fifth component, or a specific compound having a polymerizable group as an additive component.
