Abstract: Disclosed are an organic light emitting display having a touch sensor, which may achieve process simplification and cost reduction, and a method of fabricating the same. The organic light emitting display includes a compensation film having a flat surface and formed to cover dams forming a boundary with an organic encapsulation layer and the compensation film has a planarized surface between a region above the dams and a boundary region between the dams and the organic encapsulation layer (144) and may prevent cut and short-circuit of routing lines cutting across the same. Further, touch sensors are disposed on an encapsulation unit including the organic encapsulation layer and thus a separate attachment process is not required, thereby simplifying the overall process and reducing manufacturing costs of the organic light emitting display.
