ABSTRACT:
A display device includes signal lines, scanning lines, pixel switches, display pixels, and a signal line driving circuit which supplies analog video signals to the signal lines. Each of the display pixels comprises one of three types of luminescent element, the three types of luminescent element being arrayed in a scanning line direction. The driving circuit includes a conversion circuit which is arranged to divide the signal lines into signal line blocks each having a predetermined number of signal lines, converts an external digital signal for each signal line block by means of a digital-to-analog converter into an analog signal based on gradation reference voltage groups corresponding to the type, and serially outputs the analog signal as the analog video signal, and a signal line selection circuit which sequentially distributes the analog video signal to related signal lines of the signal line block.
