The subject is to provide a liquid crystal composition that satisfies at least one of characteristics such as a high maximum temperature of the nematic phase, a low minimum temperature of the nematic phase, a small viscosity, a suitable optical anisotropy, a large negative dielectric anisotropy, a large specific resistance, a high stability to ultraviolet light and a high stability to heat, or that is suitably balanced regarding at least two of the characteristics. The subject is also to provide the AM device that has a short response time, a large voltage holding ratio, a large contrast ratio, a long service life, and so forth. The invention provides a liquid crystal composition having a negatively dielectric anisotropy containing a specific compound having a negatively large dielectric anisotropy as a first component, and a specific compound having a negatively large dielectric anisotropy as a second component, and provides a liquid crystal display device containing this composition.
A liquid crystal composition having a negatively dielectric anisotropy containing at least one compound selected from the group of compounds represented by formula (1) as the first component, and at least one compound selected from the group of compounds represented by formula (2) as the second component:
