The invention provides a liquid crystal compound having stability to heat, light and so forth, a wide temperature range of a nematic phase, a small viscosity, a large optical anisotropy and a suitable elastic constant K33 (K33: bend elastic constant), and further having a suitable and negative dielectric anisotropy and an excellent compatibility with other liquid crystal compounds, and provides a liquid crystal composition having a small viscosity, a large optical anisotropy, a suitable elastic constant K33, a suitable and negative dielectric anisotropy, and further having a low threshold voltage, a high maximum temperature of a nematic phase and a low minimum temperature of the nematic phase. In a specific structure having phenylene in which hydrogen on the benzene ring is replaced by fluorine, a three-ring liquid crystal compound having fluorine at a lateral position, and a liquid crystal composition containing the compound are prepared.
