Abstract: Disclosed are an organic light emitting display having touch sensors, which may achieve process simplification and cost reduction, and a method of fabricating the same. The organic light emitting display includes a plurality of touch electrodes disposed on an encapsulation unit disposed so as to cover light emitting elements, the touch electrodes are formed through a low-temperature deposition process and may thus have amorphous characteristics so as to prevent damage to an organic light emitting layer during formation of the touch electrodes, and the touch electrodes are disposed on the encapsulation unit without a separate attachment process and may thus simplify the overall process and reduce manufacturing costs.
