摘要： A liquid crystal compound, a liquid crystal composition, and a liquid crystal electric optical device having a low rotational viscosity (γ1) and appropriate elastic constants. A fluorine-containing liquid crystal compound represented by formula (1). R1-(A1-Z1)a-(A2-Z2)b-(A3-Z3)c-A4-(CH2)n-CF═CF—R2 (1), R1 is a hydrogen atom, a halogen atom, or an alkyl group, R2 is a halogen atom or an alkyl group that may be halogen-substituted or which may include a (thio)ether group, A1 to A4 may be a phenylene group or a cyclohexylene group that may be halogen-substituted or which may include a (thio)ether group, Z1 to Z3 are a single bond, —O—, —S—, or a divalent aliphatic hydrocarbon group that may be halogen-substituted or which may include a (thio)ether group. n is an integer from 0 to 3, and a, b, and c are 0 or 1, provided that a+b+c is 1 or greater.
