Abstract: A liquid crystal composition that satisfies a plurality of characteristics in characteristics such as a high maximum temperature of a nematic phase, a low minimum temperature of the nematic phase, small viscosity, large optical anisotropy, large dielectric anisotropy (1 kHz and 20 GHz), large specific resistance, high stability to ultraviolet light and high stability to heat, and that can be used in the form of a millimeter wave phase or microwave phase antenna. The liquid crystal composition contains at least two specific compounds having the large optical anisotropy and the large dielectric anisotropy as a first component, and a specific compound having a wide nematic phase and capable of adjusting suitable optical anisotropy as a second component, and may contain such a component compound that can finely control the characteristics of the composition.
