A method of driving a display unit having matrix-arranged pixel electrodes each connected via a capacitor to a first line, each pixel electrode being connected to a switching element which is electrically connected to an image signal line and scan signal line, and display material held between the pixel electrode and opposing electrode and being AC driven, wherein an image signal voltage is transmitted to the pixel electrode during an on-period of the switching element, and a modulating signal with its voltage reversing alternately for each field is applied to the first line during an off-period of the switching element, thereby changing the potential of the pixel electrode so that the changed potential is superposed upon, or cancelled out from, the image signal voltage, the resultant voltage being applied across the display material.
