The invention discloses a liquid crystal compound containing cyclobutyl and difluorometheneoxy. The compound is shown as the formula I. In the molecular structure of the compound shown as the formula I, the liquid crystal compound containing a cyclobutane end group and a difluorometheneoxy linking group (-CF2O-) not only has higher dielectric anisotropy delta epsilon, and more importantly, also has higher response speed t, lower rotary viscosity gamma 1 and better low-temperature performance, and for formulation of the liquid crystal compound, the performance has important significance. |
