Abstract

To provide a liquid crystal composition satisfying at least one characteristic such as high maximum temperature of nematic phase, low minimum temperature thereof, small viscosity, suitable optical anisotropy, large negative dielectric anisotropy and specific resistance, high stability to ultraviolet light and heat; a liquid crystal composition having a suitable balance regarding at least two thereof; and an AM device including the composition. The liquid crystal composition has nematic phase, and contains as a first component a specific antioxidant having high compatibility with the composition and an excellent antioxidant function, and may contain a specific component having high maximum temperature or small viscosity as a second component, a specific component having high maximum temperature or large dielectric anisotropy as a third component, a specific component having large negative dielectric anisotropy as a fourth component, and a specific antioxidant as a fifth component, and a liquid crystal display device includes the composition.
