PURPOSE: A driving device for a light emitting display panel is provided to effectively apply a reverse bias voltage to a light emitting element through a drive TFT(Thin Film Transistor) by providing the driving device for the light emitting display of an active matrix type. CONSTITUTION: A driving device for a light emitting display panel includes a light emitting element(14), a control TFT(11), and a power circuit. The power circuit outputs a power source voltage level of which potential is positive or negative with respect to a reference potential. The power circuit is designed to supply a power source voltage level of positive potential to one terminal functioning as the anode of the luminescent element when a forward-directional electric current is fed to the luminescent element, and is arranged to supply a power source voltage level of negative potential to the other terminal functioning as the cathode of the luminescent element. When a reverse bias voltage is fed, the power source circuit supplies a power source voltage level of negative potential to the one terminal functioning as the anode of the luminescent element and a power source voltage level of positive potential to the other terminal functioning as the cathode of the luminescent element.
