The invention is to provide a liquid crystal composition that satisfies at least one of characteristics such as 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 to ultraviolet light and a high stability to heat, or that is suitably balanced regarding at least two of the characteristics. The invention is to provide an 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 is a liquid crystal composition that has a nematic phase and includes a specific four-ring compound having a high maximum temperature and a large optical anisotropy as a first component, and a specific four-ring compound having a large dielectric anisotropy as a second component, and is a liquid crystal display device containing this composition.
A liquid crystal composition that has a nematic phase and includes at least one compound selected from the group of compounds represented by formula (1) as a first component and at least one compound selected from the group of compounds represented by formula (2) as a second component, wherein the ratio of the first component is in the range of 3% by weight to 30% by weight, based on the total weight of the liquid crystal composition:
