[0163] First, a first embodiment of the present invention will be described with reference to FIGS. 7 and 8. A liquid crystal display device according to this embodiment comprises a display section 200, an image signal drive circuit 201, a scan signal drive circuit 202, a common electrode potential control circuit 203, and a synchronous circuit 204. The display section 200 comprises scan electrodes 212, image signal electrodes 211, a plurality of pixel electrodes 214 arranged in a matrix, a plurality of switching elements 213 for transmitting an image signal to the pixel electrodes 214, and a common electrode 215. The common electrode potential control circuit 203 changes the electric potential of the common electrode 215 into a pulse shape, after the scan signal drive circuit 202 has scanned all the scan electrodes 212 and the image signal has been transmitted to the pixel electrodes 214.
