The present invention relates to a liquid crystal compound for liquid crystal display. More particularly, the present invention provides a vinylcyclohexylbenzene, its derivatives and the preparation method thereof where the present invention produces only trans-isomer by using Heck coupling reaction instead of Wittig reaction in the introduction to ethenyl group in the central backbone in the preparation process of intermediate. The liquid crystal compound can make the liquid crystal composition have a wide mesophase range and low viscosity.
