It is an object of the present invention to provide a liquid crystal composition with high response speed without lowering various characteristics of a liquid crystal, such as voltage holding rate and phase transition temperature. One feature of the invention is that a nematic liquid crystal and an inert fluid containing fluorine (C.sub.mF.sub.n or C.sub.mF.sub.nO (n and m are natural numbers)) are mixed. Another feature of the invention is that a content of a fluorine-based inert solution (C.sub.mF.sub.n or C.sub.mF.sub.nO (n and m are natural numbers)) is 10 wt % or more to 60 wt % or less with respect to the nematic liquid crystal.
