Abstract: A compound having large refractive index anisotropy (?n), the effect of increasing the phase transition temperature of a liquid crystal phase, and high solubility, and showing large dielectric anisotropy (??) in a high frequency region, a composition containing the compound, a liquid crystal composition, and a device using the liquid crystal composition. The compound has large refractive index anisotropy ?n, sufficiently high Tn-i, and high compatibility with a liquid crystal composition, and shows large dielectric anisotropy in a high frequency region, and is thus useful for a material of an element of a device such as a high-frequency phase shifter, a phased array antenna, an image recognition device, a distance measuring device, a liquid crystal display device, a liquid crystal lens, a birefringent lens for stereoscopic image display.
