Abstract: The present disclosure relates to an organic light emitting display device which is implemented to reduce or suppress the residual image and the flicker. According to an embodiment, a circuit includes an organic light emitting diode disposed between a first node and a first power source, a driving transistor disposed between the first node and a second power source and driving the organic light emitting device, a first transistor transmitting a data signal to the driving transistor, and a first control transistor disposed between the first node and a second node. The first control transistor applies a reverse current to the driving transistor during a first period and holes accumulated on the active layer of the driving transistor are removed during the first period, whereby a current path efficiency is improved.

Abstract: Provided is an organic light emitting display device including a plurality of sub pixels. Areas of emission regions of green sub pixels of the plurality of sub pixels are the same as or larger than an area of an emission region of at least one non-green sub pixel of the plurality of sub pixels. Also the organic light emitting display device includes an area of an emission region of a green sub pixel having a low luminance lifetime being the same as or larger than areas of emission regions of non-green sub pixels. Accordingly, it is possible to make the luminance lifetime of the green sub pixel and the luminance lifetimes of the non-green sub pixels uniform. Further, it is possible to minimize a color change of the organic light emitting display device.
