Abstract
An organic EL display device includes display pixels forming a display screen, scanning lines disposed along rows of the display pixels, signal lines disposed along columns of the display pixels, and a power supply section which supplies a power-supply voltage to the display pixels. Each of the display pixels includes a luminous element, a pixel switch which receives a video signal from a corresponding one of the signal lines in response to a scanning signal from a corresponding scanning line and a driving element which is connected between the luminous element and the power supply section to supply a driving current corresponding to the video signal from the pixel switch to the luminous element. Particularly, each luminous element is connected to the power supply section via a dimmer switch portion.
