Abstract
An active type of display panel arranged with light-emitting elements such as organic electroluminescent elements, capable of effecting correct tonal display even during a long-time use, a display device using the display panel and a method of driving the display panel. In each of pixel portions on the display panel, a driving element is activated according to a data signal, to supply a light-emitting element with a drive current in an amount corresponding to the data signal. The data signal is corrected such that the drive current becomes equal to a current corresponding to a light-emitting luminance represented by the data signal.
