Abstract
A liquid crystal display device includes a display section, an image signal drive circuit, a scan signal drive circuit, a common electrode potential control circuit, and a synchronous circuit. The display section has scan electrodes, image signal electrodes, a plurality of pixel electrodes arranged in a matrix, a plurality of switching elements for transmitting an image signal to the pixel electrodes, and a common electrode. The common electrode potential control circuit changes an electric potential of the common electrode into a pulse shape, after the scan signal drive circuit has scanned all the scan electrodes and the image signal has been transmitted to the pixel electrodes. Otherwise, the image signal is overdriven. Otherwise, torque for returning to a no-voltage-application state is increased.
