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