Abstract: An organic light-emitting display device includes a display panel, a source driver, a scan driver, and a timing controller. A gate node of a second transistor of an (N?1)-th sub pixel and a gate node of a first transistor of an N-th sub pixel are connected in common such that the second transistor of the (N?1)-th sub pixel and the first transistor of the N-th sub pixel are simultaneously turned on by a scan signal supplied to the second transistor of the (N?1)-th sub pixel. Accordingly, it is possible to decrease a size of the scan driver and a bezel area.
