PROBLEM TO BE SOLVED: To provide general physical properties necessary for a compound, stability to heat, light, etc., small viscosity, appropriate optical anisotropy, appropriate dielectric anisotropy, wide temperature range of nematic phase, and other liquid crystal properties The present invention provides a liquid crystalline compound having excellent compatibility with a compound, and particularly having a wide temperature range of a nematic phase. The compound is represented by the following formula (1). For example, Ra and Rb are independently alkyl having 1 to 20 carbons; ring A 1 is 1,4-cyclohexylene or 1,4-phenylene; Z 1 is a single bond or having 1 to 4 carbons Y 1 is hydrogen or halogen; Rc is alkyl having 1 to 4 carbon atoms; m is 0, 1 or 2, and the sum of m is 0, 1 or 2.
