Abstract: An organic light emitting display device that can display an image with desired luminance is disclosed. The organic light emitting display device includes: pixels at crossing regions of scan lines and data lines; first control transistors between a first power supply (for supplying current to the pixels) and the pixels in the odd-numbered rows (or, in a second embodiment, the even-numbered rows); and second control transistors between the first power supply and the pixels in the even-numbered rows (or, in the second embodiment, the odd-numbered rows). The first control transistors are configured to turn on and off in alternation with the second control transistors during a scan period of one frame period.
