Shown is a liquid crystal compound satisfying at least one of physical properties such as high stability to heat or light, a high clearing point (or high maximum temperature), 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, etc., a liquid crystal composition containing this compound, and a liquid crystal display device containing this composition. A compound is represented by formula (1). In formula (1), R1 is hydrogen, fluorine, alkyl or the like; ring A1 and ring A2 are independently 1,4-cyclohexylene, 1,4-phenylene or the like; Z1, Z2 and Z3 are independently a single bond, -COO- or the like; X1 is hydrogen, fluorine, -CF3, or -OCF3; L1 and L2 are independently hydrogen or fluorine; and a is 0 or 1, and b is 0 or 1.
