Abstract: Disclosed are an organic light emitting display device and a method of manufacturing the same to reduce thickness and weight. The organic light emitting display device with a touch sensor removes the necessity of an additional adhesion process by directly forming a touch sensing electrode and a touch driving electrode arranged in parallel and a color filter on an encapsulation layer covering a light emitting device, thereby simplifying a manufacturing process and reducing manufacturing costs.

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.
