Claim:
A liquid crystal display device comprising: a liquid crystal display section having a plurality of scan electrodes, a plurality of image signal electrodes which are perpendicular to the scan electrodes, a plurality of pixel electrodes arranged in a matrix with the scan electrodes and the image signal electrodes, a plurality of switching elements for transmitting an image signal to the plurality of pixel electrodes, a plurality of common electrodes which are next to the plurality of pixel electrodes and a plurality of storage capacitor electrodes; an image signal drive circuit coupled to the liquid crystal display section; a scan signal drive circuit coupled to the liquid crystal display section; a synchronous circuit coupled to the image signal drive circuit and the scan signal drive circuit; and a common electrode potential control circuit, coupled to the synchronous circuit and the liquid display section, for changing an electric potential of the common electrode into a pulse shape, just after the scan signal drive circuit has scanned all the scan electrodes and the image signal has been transmitted to the pixel electrodes, wherein electric potentials of the image signal, during an electric charge hold drive, are never an electric potential of the image signal in a stable display state during static drive, wherein the sum of electric charge held between the pixel electrodes and the common electrodes and electric charge held between the pixel electrodes and the storage capacitor electrodes, is approximately equal to hold data.
