ABSTRACT:
A vertically aligned type liquid crystal display includes a liquid crystal layer containing vertically aligned liquid crystal molecules and disposed between a plurality of pixel electrodes and a common electrode, wherein the orientation of the liquid crystal molecules is controlled by electric field, and wherein an refraction anisotropy .DELTA.n of the liquid crystal used in the liquid crystal layer and a cell gap d [.mu.m] which is a distance between the pixel electrodes and the common electrode are selected to satisfy .DELTA.n.multidot.d.ltoreq.-0.033*d+0.88. With this configuration, a sufficiently wide range of driving voltages and an improved response speed are achieved.
