Abstract

In a method of driving a liquid crystal device, etc., and a display device, particularly those for gradation dispaly, the present invention aims at providing a driving method of a liquid crystal device, etc., and a display device capable of satisfactorily effecting gradation display without causing insufficient contrast, flickers, cross-talk, etc. When effecting multiplex driving of a liquid crystal device, etc., having a liquid crystal layer sandwiched between a substrate having scanning electrodes X1, X2,... and a substrate having signal electrodes X1, Y2,..., the present invention simultaneously selects sequentially a plurality of scanning electrodes, divides the selection period into a plurality of periods, and applies a weighted voltage, which is weighted in accordance with desired display data, in each of the divided selection periods so as to effect gradation display.
