Abstract
An organic electroluminescent display that can prevent decreases in an average luminance of an organic electroluminescent element thereof includes: a data line to supply a data signal; a scan line to supply a scan signal; a first switching element having a control electrode electrically coupled to the scan line, to transfer the data signal from the data line; a first driving transistor having a control electrode electrically coupled to the first switching element, to control a driving current of a first voltage line; a first capacitive element having a first electrode electrically coupled to the first voltage line and having a second electrode electrically coupled to a control electrode of the first driving transistor; an organic electroluminescent element, electrically coupled to the first driving transistor and a third voltage line, to display an image in response to a current supplied from the first driving transistor; and a second voltage line to supply a reverse bias voltage of a second voltage line to the organic electroluminescent element.
