Liquid crystal composition and liquid crystal elements, sensors, liquid crystal lenses, optical communication equipment and antennas using the liquid crystal composition.

摘要

The present invention has a high liquid crystal phase upper limit temperature (TNI ), a high refractive index anisotropy (Δn), and a liquid crystal material capable of greater phase control with respect to microwave or millimeter electromagnetic waves. , A nematic liquid crystal composition having a low threshold voltage (Vth) and a liquid crystal element, a sensor or an antenna using the nematic liquid crystal composition. Specifically, one or more compounds represented by the general formula (i-1), and the general formula (i-2-1a), the general formula (i-2-1b), and the general formula (i). A liquid crystal composition comprising one or more compounds selected from -2-1c) and one or more compounds represented by the general formula (ii). be.
