Abstract: PURPOSE: An electro luminescence displayer is provided to improve an action characteristic by actuating a drive transistor in a saturation area of drive current. CONSTITUTION: A switching transistor(T21) transmits a data signal selected by a scanning signal. A drive transistor(T22) is driven by the data signal so that the drive transistor flows a drive current by a voltage difference between a first power voltage terminal(Vdd) and a second power voltage terminal(Vss). A capacitor is connected between a source of the switching transistor and a gate of the drive transistor. The capacitor keeps regularly a gate voltage to drive the drive transistor even if the data signal is isolated. An electro luminescent diode(ED2) is luminesced by the drive current of the drive transistor. Thus, as the drive transistor actuates in an area where the drive current is sufficiently saturated, an action characteristic is improved. Further, the life of the electro luminescence display device is extended by preventing an electric charge from being accumulated in the EL(electro luminescence) diode.
