Abstract:
1. A liquid crystal display device comprising a display section, an image signal drive circuit, a scan signal drive circuit, an electrode potential control circuit, and a synchronous circuit wherein the display section includes: a twisted nematic liquid crystal having a response speed faster than one frame interval; scan electrodes which are scanned by the scan signal drive circuit; image signal electrodes which are driven by the image signal drive circuit; a plurality of pixel electrodes arranged in a matrix; a plurality of switching elements for transmitting an image signal of the image signal electrodes to the pixel electrodes; and a storage capacitor electrode to be controlled by the electrode potential control circuit, the electrode potential control circuit changes an electric potential of the storage capacitor 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, and the electric potential of the storage capacitor electrode changed into the pulse shape is an electric potential that does not reset the display of the display section.
