Abstract
A liquid crystal composition satisfying at least one of characteristics such as a high maximum temperature of a nematic phase, a low minimum temperature of the nematic phase, a small viscosity, a large optical anisotropy, a large negative dielectric anisotropy, a large specific resistance, a high stability to ultraviolet light, a high stability to heat and a short helical pitch is provided, wherein the liquid crystal composition has a negative dielectric anisotropy and contains a specific optically active compound as a first compound, a specific compound having a large negative dielectric anisotropy as a second component, and may contain a specific compound having a high maximum temperature or a small viscosity as a third component, a specific compound having a large negative dielectric anisotropy as a fourth component and a specific optically active compound as a fifth component, and a liquid crystal display device that contains the composition.
