Abstract
A problem is to provide a liquid crystal compound satisfying at least one physical property such as high stability to heat and light, a high clearing point (or high maximum temperature), a low minimum temperature of a liquid crystal phase, small viscosity, suitable optical anisotropy, large dielectric anisotropy, a suitable elastic constant and excellent compatibility with other liquid crystal compounds, a liquid crystal composition containing the compound and a liquid crystal display device including the composition. A solution is a compound represented by formula (1). In which, Ris alkyl having 1 to 10 carbons or the like; Z, Zand Zare independently a single bond, —COO—, —OCH—, —CFO— or the like, and at least one of Z, Zand Zis —CFO—; Xis hydrogen, fluorine, —CFor —OCF; and L, L, Land Lare independently hydrogen, fluorine or chlorine.
