Abstract

A composition having a high Δn, a wide temperature range of a liquid crystal phase, low viscosity, good solubility at a low temperature, high resistivity, a high voltage holding ratio, and stability against heat and light; a liquid crystal composition containing the composition, the liquid crystal composition having a good lens effect and good chemical stability; a liquid crystal display device including the liquid crystal composition; and a liquid crystal lens including the liquid crystal composition. The liquid crystal composition contains one or two or more compounds represented by general formula (i) and one or two or more compounds represented by general formula (ii).
