PROBLEM TO BE SOLVED: To provide a low-viscosity and negative dielectric anisotropy value having a large absolute value, a controlled optical anisotropy value, a high specific resistance value and a high voltage holding ratio. Another object of the present invention is to provide a liquid crystal compound which is stable against heat or ultraviolet irradiation, a liquid crystal composition containing the compound, and a liquid crystal display device prepared using the liquid crystal composition. SOLUTION: A liquid crystal compound having a 2,3-difluorocyclohexa-1,3-diene-1,4-diyl group in a skeletal structure, a liquid crystal composition containing the same, and a liquid crystal composition containing the same The liquid crystal display element created. |
