PROBLEM TO BE SOLVED: To provide a high maximum temperature of a nematic phase, a low minimum temperature of a nematic phase, a small viscosity, a large optical anisotropy, a large dielectric anisotropy, a large specific resistance, a high stability against ultraviolet rays, a high stability against heat, etc. Provided is a liquid crystal composition having a suitable balance of at least one or two characteristics. An AM device having a short response time, a large voltage holding ratio, a large contrast ratio, a long lifetime, and the like is provided. A specific compound having a large negative dielectric anisotropy as a first component, a specific compound having a large negative dielectric anisotropy and a high optical anisotropy as a second component, and a third component A specific compound having a high maximum temperature or a small viscosity and a specific compound having a large negative dielectric anisotropy as the fourth component, and the proportion of the second component is 10% by weight based on the total weight A liquid crystal composition having negative dielectric anisotropy as described above, and a liquid crystal display device containing the composition.
