Subject The subject 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 suitable 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 two or more characteristics. The subject 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. Means for Solving the Subject The invention provides a liquid crystal composition that has a nematic phase and includes a specific four-ring compound having a high maximum temperature as a first component, a compound having a specific bonding group and a large dielectric anisotropy as a second component, and a specific two-ring compound having a small viscosity as a third component, and provides a liquid crystal display device containing the composition.
