Zusammenfassung:	The present invention relates to a liquid crystal compound having a structure represented by formula I, wherein R is selected from H, and unsubstituted alkyl or alkoxy, or the alkyl or alkoxy in which one or more Hs are substituted by halogens and 1 to 12 carbon atoms are contained; A1, A2 and A3 are separately selected from a single bond, 1,4-cyclohexyl, and 1,4-phenyl; hydrogen in the 1,4-phenyl can be separately substituted by one or more halogens; and Z1 and Z2 are separately selected from a single bond and -(CH2)2-. The compound in the present invention has the characteristics of low rotary viscosity, high dielectric anisotropy, good intersolubility and stable performance; the compound can reduce a drive voltage of a device after the compound is applied to a composition, and has a wide application prospect.
