An organic light emitting display device may include a pixel portion including a plurality of pixels, which are coupled to scan lines and data lines, a scan driver adapted to provide scan signals to the scan lines, a first transistor group adapted to test the plurality of pixels, the first transistor group being directly connected to first ends of the data lines, a second transistor group adapted to test the plurality of pixels, the second transistor group being connected to second ends of the data lines, a data distributor coupled between the second ends of the data lines and the second transistor group, a first wire group extending in a first direction at an outer area of the light emitting display device, and a second wire group extending in a second direction at the outer area of the light emitting display device.
