<p>A light-emitting display device which suppresses the influence of characteristic variations of a driving transistor and a characteristic shift caused by electrical stress is disclosed. The device includes multiple pixels including an organic EL element (OLED) which emits light at a luminance determined based on the supplied current and a drive circuit for supplying current to the OLED based on a control voltage from a data line. The drive circuit includes a driving transistor (D-TFT) for the OLED, a capacitor element, and multiple switch elements. D-TFT has a source terminal connected with an anode terminal of OLED. The capacitor and switch elements operate so that, when current is supplied from the drive circuit to the OLED, a voltage difference between the gate and source terminals of the D-TFT is a sum of the threshold voltage of the driving transistor and a voltage determined from the voltage of the drain terminal of the driving transistor and the control voltage during a current setting period.</p> |
