Abstract: An organic light emitting display device is provided to prevent a motion blur phenomenon and improve a high contrast ratio by controlling a ratio of a light emitting driving period to a negative annealing period variously. A first switching element is connected between a data lien and a first power voltage line and transmits a data signal. A scan line is electrically connected to a control electrode. A driving transistor is electrically connected between a first power voltage line and a second power voltage line. The first switching element is electrically connected to the control electrode. An organic light emitting device is electrically connected to the driving transistor and displays the image by the current supplied by the driving transistor. A first capacitance device is electrically connected between the control electrode of the driving transistor and the first switching element. A second capacitive device is electrically connected between the first capacitance device and the second power voltage line. A second switching element is electrically connected between the control electrode of the driving transistor and the first power voltage line. A third switching element is electrically connected between the first switching device and the driving transistor. A fourth switching element is electrically connected between the control electrode of the driving transistor and the second power voltage line. The fifth switching element is electrically connected between the driving transistor and the second power voltage line.
