Abstract
A liquid crystal compound is provided that has excellent characteristics, such as a negatively large dielectric anisotropy. A liquid crystal composition containing the compound, and a liquid crystal display device containing the composition are also provided. A compound having the three factors, i.e., (1) a tetrahydropyran ring, (2) —CHO— or —OCH— and (3) exhibits excellent characteristics including a negatively large dielectric anisotropy. The use of the compound having the characteristics provides an excellent liquid crystal composition and an excellent liquid crystal display device.
