Abstract:
An active matrix type display device comprising:a display panel includingan array substrate having pixel electrodes which are connected in vicinity of respective intersection points between a plurality of signal lines and a plurality of scanning lines, which are arranged so as to intersect mutually, via switching elements,an opposing substrate which is arranged so as to oppose to the array substrate, andan optical modulating layer which is held between the array substrate and the opposing substrate;a signal driving means for supplying a video signal voltage each of the signal lines; anda scanning line driving means for supplying sequentially a scanning pulse to each of the scanning lines based on a vertical clock signal and a vertical start signal, the scanning pulse containg a first voltage for turning on the switching elements in a first voltage period, a second voltage for turning off the switching elements, and a third voltage for compensating electrical potential shifts of the pixel electrodes;wherein each of the pixel electrodes, which is connected to one of the scanning lines of the display panel via one of the switching elements, are arranged to electrically form capacitances with neighboring another one of the scanning lines via dielectric portions, andthe scanning line driving means sets an initial section of change, in which the scanning pulse in the first voltage period is varied to the first voltage, to a predetermined voltage by which the switching elements are turned off.
