Abstract
A liquid crystal compound is provided that satisfies 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 negative dielectric anisotropy, a suitable elastic constant and good compatibility with other liquid crystal compounds, a liquid crystal composition containing the compound, and a liquid crystal display device including the composition. The liquid crystal compound is represented by formula (1): in which, Rand Rare alkyl having 1 to 10 carbons; ring A, ring Aand ring Aare 1,4-cyclohexylene, 1,4-phenylene; and ring Nis 2,3-difluoro-1,4-phenylene; G is a divalent group represented by formula (pr-1) or (pr-2); in which, Z, Z, Zand Zare a single bond; and a, b and c are 0, 1 or 2.
