  A liquid crystal compound is to be obtained that has stability to heat, light and so forth, a high clearing point, a suitable optical anisotropy, a large negative dielectric anisotropy, and excellent compatibility with other liquid crystal compounds. A liquid crystal composition containing the compound is also to be obtained that has a low viscosity, a suitable optical anisotropy, a suitable negative dielectric anisotropy, a low threshold voltage, a high maximum temperature of a nematic phase (phase transition temperature from a nematic phase to an isotropic phase), and a low minimum temperature of a nematic phase. A compound having a hydrocoumarin skeleton is synthesized, and a liquid crystal composition containing the compound is produced.
