Abstract
A liquid crystal composition satisfying at least one of characteristics such as a high maximum temperature of nematic phase, a low minimum temperature of nematic phase, small viscosity, suitable optical anisotropy, large dielectric anisotropy, large specific resistance, and high stability to UV light and heat, or having a suitable balance regarding at least two thereof, and an AM device including the composition and having a short response time, a large voltage holding ratio, a large contrast ratio or a long service life are shown. The composition has the nematic phase and contains a specific compound having large dielectric anisotropy as a first component, a specific compound having small viscosity as a second component, and may contain a specific compound having a high maximum temperature or small viscosity as a third component and a specific compound having large dielectric anisotropy as a fourth component. The LCD device includes the composition.
