Abstract: Disclosed is an organic light emitting display having reduced thickness and weight. The organic light emitting display with a touch sensor removes the necessity of an additional adhesion process by directly forming a touch sensor including a touch sensing line and a touch driving line and a color filter on the encapsulation layer covering a light emitting device, thereby simplifying a manufacturing process and reducing manufacturing costs.

Abstract: 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.

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.
