<p>The subject is to provide a liquid crystal composition that satisfies at least one characteristic 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 negatively 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 characteristics thereof. The subj ect 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 provides a liquid crystal composition having a negative dielectric anisotropy that includes a specific compound having 1-pyran-2,5-dyil as a first component, and a specific compound having a negatively large dielectric anisotropy as a second component , and provides a liquid crystal display device containing the composition.</p> |
