<P>PROBLEM TO BE SOLVED: To provide an organic electroluminescence display that suppresses an afterimage phenomenon due to a decrease in efficiency of an organic electroluminescence element by adjusting the amount of current transmitted to the organic electroluminescence element and compensates for the threshold voltage of a driving transistor. <P>SOLUTION: The organic light emitting display includes a first switching element including a control electrode electrically coupled to a scan line and between a data line and a first source voltage line, a driving transistor electrically coupled between the first source voltage line and a second source voltage line, a second switching element including a control electrode electrically coupled to a light emission control line and between the first source voltage line and the driving transistor, a third switching element including a control electrode electrically coupled to the scan line and between the second switching element and the driving transistor, a first capacitor that is electrically coupled between the first source voltage line and the control electrode of the driving transistor, a second capacitor that is electrically coupled between the first capacitor and the second switching element, and an electroluminescence element electrically coupled between the driving transistor and the second source voltage line. <P>COPYRIGHT: (C)2008,JPO&INPIT |
