To provide a liquid crystal compound having a large negative value of dielectric anisotropy (Δ∈). A compound is represented by formula (1): wherein, in formula (1), one of Y1 and Y2 is fluorine, and the other is CF2H or CF3; G is a ring represented by formula (pr-1) or formula (pr-2): wherein A1 to A3 are independently 1,4-cyclohexylene or 1,4-phenylene; Ra and Rb are independently hydrogen, alkyl having 1 to 20 carbons, or the like; Z0, and Z1 to Z3 are independently a single bond, —(CH2)2—, —CH═CH—, —CF2O—, —OCF2—, —CH2O—, —OCH2—, —COO— or —OCO—; j, m and n are an integer from 0 to 2, and a sum of j, m and n is 0, 1 or 2, however, when m is 0, Y1 is CF2H or CF3, Y2 is fluorine, and Z0 is a single bond, G is a ring represented by formula (pr-1).
