A method of driving an electrooptical device having signal electrodes, first and second groups of scan electrodes, pixel electrodes, first and second groups of nonlinear resistance elements, each nonlinear resistance element in the first and second groups of elements being connected between a respective pixel electrode and a scan electrode in each of the first and second groups of electrodes respectively, and electrooptical material interposed between said signal electrodes and the respective pixel electrodes. The method comprises the steps of applying selected voltages which include an operation voltage value Vop to the first and second scan electrodes during a selected period wherein the polarity of the value Vop applied to the first scan electrode is opposite to the polarity of that applied to the second scan electrode; applying non-selected voltages to the first and second scan electrodes during a non-selected period; and applying data voltages to the signal electrodes for controlling charge injected into the electrooptical material during the selected period. With this driving method, even upon inversion of she driving waveform, the screen contrast can be kept uniform and a display can be presented with high picture quality.
