Abstract
An organic light emitting display that can minimize degradation of a drive transistor comprising a first switching element whose control electrode is electrically coupled to a scan line, being electrically coupled between a data line and a first voltage line for transmitting a data signal; a drive transistor whose control electrode is electrically coupled to the first switching element, being electrically coupled between the first and second voltage lines; an organic light emitting diode electrically coupled to the drive transistor, displaying an image by a current supplied through the drive transistor; a first capacitive element electrically coupled between the control electrode of the drive transistor and the first switching element; a second capacitive element electrically coupled between the first capacitive element and the second voltage line; a second switching element electrically coupled between the first voltage line and the control electrode of the drive transistor; a third switching element electrically coupled between the first switching element and the drive transistor; a fourth switching element electrically coupled between the control electrode of the drive transistor and the second voltage line; and a fifth switching element electrically coupled between the drive transistor and the second voltage line.
