more preferably 35 to 71 by weight if the mixing ratio is less than 20 by weight a low viscosity composition may not be obtained while if it exceeds 80 by weight the threshold voltage of the composition may become high when the fourth component is used in the present invention the mixing ratio is preferably 40 or less based upon the total weight of the resulting composition and more preferably 35 by weight or less it is possible for the liquid crystal composition of the present invention to further contain compounds besides those expressed by the above formulas 1 to 7 in suitable quantities within a range which does not harm the object of the present invention in order to adjust the threshold voltage nematic range u03b4n dielectric anisotropy viscosity etc of the resulting composition and in accordance with the objects of use of the liquid crystal display element the liquid crystal composition used in accordance of the present invention can be prepared according to a process which is conventional by itself in general there is employed a process of dissolving various components with each other at a high temperature to obtain a uniform mixture further by adding a suitable compound to the liquid crystal composition of the present invention it is possible to prepare a liquid crystal material suitable to use applications such an additive.
