Abstract
A liquid crystal composition including an antioxidant, and a liquid crystal display device containing this composition are described. The liquid crystal composition has a nematic phase, has a high solubility in a liquid crystal composition, and includes a specific antioxidant useful for preventing deterioration of the composition. The liquid crystal composition may also include a specific compound having a high maximum temperature or a small viscosity as a first component, a specific compound having a high maximum temperature or a large dielectric anisotropy as a second component, and a specific compound having a large negative dielectric anisotropy as a third component.
