ABSTRACT:
In order to provide a liquid crystal display device which uses a liquid crystal material having physical quantities set so as to contribute to high image quality by reducing crosstalk, flicker, and direct-current component shift, the liquid crystal material used in a liquid crystal display device according to the present invention has an effective dielectric constant .epsilon..sub.P in the direction of the long axis and an effective dielectric constant .epsilon..sub.V in the direction of the short axis which, if X=.epsilon..sub.P +.epsilon..sub.V and Y=.epsilon..sub.P .multidot..epsilon..sub.V, satisfy Y=A.multidot.X-B at a certain point in the ranges 9.5.ltoreq.X.ltoreq.15.5, 5.43.ltoreq.A.ltoreq.5.75, and 27.ltoreq.B.ltoreq.36.2.
