LIQUID CRYSTALLINE COMPOUND WITH NEGATIVE DIELECTRIC ANISOTROPY, LIQUID CRYSTAL COMPOSITION, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

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) -CH 2 O- or -OCH 2 - 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.
