A power supply circuit (3) supplies an output voltage (VHr) to each pixel of a display panel (1), the output voltage (VHr) corresponding to a forward voltage generated at a monitor element (Er) for monitoring R having the highest forward voltage. Accordingly, at sub-pixels producing R emission, the output voltage can compensate for the emission brightness according to the temperature characteristics and aging of organic EL elements (E1). For sub-pixels of G and B having high emission efficiencies in comparison with R, a compensation means is provided that compensates for the brightness of organic EL elements for G and B. This makes it possible to light each of the sub-pixels by the single power supply circuit (3) and to provide a display device that follows the temperature characteristics and aging of all of R, G, and B. |
