ABSTRACT:
In a spontaneous light-emitting display device operating in an active matrix mode, variations in the threshold voltages of transistors controlling the current flowing to light-emitting elements and variations in the light emission threshold voltages of the light-emitting elements are suppressed, reducing variations in the luminance of the light-emitting elements. Light-detecting elements detect light emitted by the light-emitting elements, and threshold voltages of the transistors are detected by the voltages of nodes of resistors and the light-emitting elements. Further, transistors controlled by respective signals of the light-detecting elements also detect the light emission threshold voltages of the light-emitting elements.
