Abstract

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