WIPO Patent Application WO/2021/085279

A1

In order to enable larger phase control for microwave or millimeter electromagnetic waves, the present invention provides a nematic liquid crystal composition as a liquid crystal material having a large dielectric anisotropy Δε and a large refractive index anisotropy Δn, the nematic liquid crystal composition having a wide nematic liquid crystal temperature range, being stable at low temperatures, and having high reliability against external stimuli such as heat, and also provides a liquid crystal element, a sensor, a liquid crystal lens, an optical communication device, and an antenna using the nematic liquid crystal composition. Specifically, provided are a liquid crystal composition having a liquid crystal compound represented by the general formula (i), and also a liquid crystal element, a sensor, a liquid crystal lens, an optical communication device, and an antenna using the liquid crystal composition.
