Abstract
The disclosure provides a liquid crystalline compound that has at least one of physical properties such as high stability with respect to heat and light, a high clearing point (or a high upper limit temperature), a low lower limit temperature of a liquid crystal phase, a low viscosity, suitable optical anisotropy, large negative dielectric anisotropy, a suitable elastic constant, favorable compatibility with other liquid crystalline compounds at room temperature and low temperatures, a liquid crystal composition including the compound, and a liquid crystal display element including the composition. The compound is represented by Formula (1). Here, Ris an alkyl group having 2 to 10 carbon atoms in which one —CHCH— is substituted with —CH═CH—; Ris an alkyl group having 1 to 8 carbon atoms; ring Ais 1,4-cyclohexylene; Yand Yare hydrogen or fluorine; Zis a single bond; and nis 1 or 2.
