At least one of properties such as high stability to light, high transparency, low low temperature on liquid crystal, small viscosity, suitable optical anisotropy, large dielectric anisotropy, large dielectric constant in the minor axis direction, suitable elastic constant, excellent compatibility A liquid crystal compound, a liquid crystal composition containing the compound, and a liquid crystal display element comprising the composition are provided. A compound represented by the formula (1). For example, R 1 is alkyl of 1 to 15 carbon atoms, ring A 1 to ring A 4 are 1,4-cyclohexylene or 1,4-phenylene, Z 1 to Z 4 are single bonds, - (CH 2 ) 2 -, -COO-, or -CH 2 O-, X 1 is halogen, -C≡N, -CF 3 , or -OCF 3 , L 1 and L 2 are hydrogen or Y 1 and Y 2 are fluorine; a, b, c, and d are 0 or 1, and the sum is 1 or 2. |
