Disclosed is an organic light emitting display device with a touch sensor. The display device has a touch sensor that is directly disposed on a sealing part, thus removing the necessity of an additional adhesion process, simplifying a manufacturing process and reducing manufacture cost. In addition, the display device with the touch sensor includes a display cover electrode of a display pad that is made of a same material as a conductive layer included in the touch sensor, thus preventing damage to the display pad electrode.

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 () 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.

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.

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.

A display device having touch sensors is discussed, which can achieve process simplification and cost reduction. In the display device, a black matrix including first and second black layers is arranged on an encapsulation unit arranged to cover light emitting elements, the first black layer is conductively connected to a plurality of touch electrodes and is arranged between color filters overlapping the touch electrodes, and the second black layer is arranged on a different plane from the first black layer and is arranged between color filters not overlapping the touch electrodes. Thereby, the first black layer can be used not only as the black matrix but also as the touch electrodes and thus light leakage can be prevented and an aperture ratio can be improved, and the touch sensors are arranged on the encapsulation unit without a separate attachment process and thus process simplification and cost reduction can be achieved.
