The present invention provides a nematic liquid crystal composition, and a liquid crystal element, a sensor, a liquid crystal lens, an optical communication device or an antenna using the composition, wherein the nematic liquid crystal composition is capable of responding to microwave or millimeter wave electromagnetic waves. In a liquid crystal material that has a high refractive index anisotropy Δn by performing greater phase control, the nematic liquid crystal has a wide temperature range. Specifically, a liquid crystal composition, or a liquid crystal element, a sensor, a liquid crystal lens, an optical communication device, or an antenna including a liquid crystal layer including the liquid crystal composition, and the liquid crystal composition has the general formula (i) And the compound represented by general formula (ii). |
