Abstract

An organic electroluminescent display device includes an organic electroluminescent diode receiving a driving voltage and a first ground voltage; first and second driving thin film transistors for providing a driving current to the organic electroluminescent diode; a first switching thin film transistor receiving a data voltage and switched by an nth scan signal; a second switching thin film transistor switched by a current providing signal; a third switching thin film transistor receiving a second ground voltage and switched by a selection signal; a fourth switching thin film transistor disposed among an output terminal of the second switching thin film transistor; and a first capacitor disposed among the output terminal of the first switching thin film transistor, the gate terminal of the first driving thin film transistor and the gate terminal of the second driving thin film transistor.
