Thus, according to the present invention, if power is supplied to each one end of the plurality of supplementary electrodes by using the electrode pad, the power is transmitted, at the same time, to the other ends of each of the plurality of supplementary electrodes. Therefore, the power is simultaneously supplied to each center of the plurality of driving regions regardless of the distance between the electrode pad and the driving regions. Further, as mentioned above, a voltage drop phenomenon is prevented since the light emitting unit is divided into the plurality of driving regions in which no voltage drop occurs. That is to say, uniform currents can flow on the front side of each driving region irrespective of the distance between the supplementary electrodes and the driving regions. Consequently, a large-scaled organic light emitting device which can show uniform brightness properties in the overall light emitting unit can be manufactured. 1.
