Zusammenfassung:	Provided in the present invention is a liquid crystal composition, which comprises at least one or more compounds of general formula I, one or more compounds of general formula II, and one or more compounds of general formula III, wherein in general formula I, R1 represents an alkyl group having 1-7 carbon atoms or an alkenyl group having 2-7 carbon atoms, and n represents 0, 1 or 2; in general formula II, R2 and R3 each independently represent an alkyl group having 1-7 carbon atoms, an alkoxy group having 1-7 carbon atoms or an alkenyl group having 2-7 carbon atoms; and in general formula III, R4 and R5 each independently represent an alkyl group having 1-7 carbon atoms, an alkoxy group having 1-7 carbon atoms or an alkenyl group having 2-7 carbon atoms, n represents 1 or 2, and formula 1 represent one or more of formula 2, formula 3 and formula 4. The liquid crystal composition of the present invention has a low rotary viscosity, a large elastic constant, large optical anisotropy, good low-temperature inter
