An active matrix display device comprises a plurality of pixels which are arranged in the form of a matrix on a substrate and each of which includes a display element and a pixel circuit which supplies the display element with a drive current, video signal lines arranged along the pixels, and a video signal driver which, after the supply of base currents to the video signal lines, supplies the pixels with gradation currents through the video signal lines. The pixel circuit includes a pixel switch which controls whether or not to select the pixel, stores the difference current between the gradation and base currents when the pixel is selected and outputs the stored difference current to the display element as the drive current when the pixel is nonselected.
