ABSTRACT:
A liquid crystal composition is provided that satisfies at least one characteristic among the 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 is properly balanced regarding at least two characteristics. An AM device is provided that has a short response time, a large voltage holding ratio, a large contrast ratio, a long service life and so forth. The liquid crystal composition contains a specific compound having especially negatively large dielectric anisotropy as the first component, a specific bicyclic compound having a small viscosity as the second component, a specific compound having a high maximum temperature as the third component, a specific compound having a negatively large dielectric anisotropy, a low minimum temperature as the fourth component. The liquid crystal composition has a negative dielectric anisotropy. The liquid crystal display device contains the liquid crystal composition.
