Provision of a liquid crystal compound, a liquid crystal composition, and a liquid crystal electro-optical element with a low rotational viscosity (γ1) and an appropriate elastic constant. The fluorine-containing liquid crystal compound represented by Formula (1). R 1- (A 1 -Z 1 ) a- (A 2 -Z 2 ) b- (A 3 -Z 3 ) cA 4- (CH 2 ) n-CF = CF-R 2 (1) R 1 : a hydrogen atom, a halogen atom, an alkyl group. R 2 : An alkyl group in which a halogen atom, a halogen atom may have a substituted or (thio) ether group. A 1 to A 4 : The phenylene group and cyclohexylene group in which the halogen atom may have a substituted or (thio) ether group. Z 1 to Z 3 : A divalent aliphatic hydrocarbon group in which a single bond, -O-, -S-, or a halogen atom may have a substituted or (thio) ether group. n: integer of 0-3. a, b, c ： 0, 1. However, a + b + c is 1 or more. |
