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 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 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.

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.

Abstract: Disclosed are an organic light-emitting display device and a method of manufacturing the same. In the organic light-emitting display device, a first protrusion is provided to protrude from a planarization layer, which has a pixel contact hole configured to expose a thin-film transistor disposed on a substrate, toward a cathode electrode of an organic light-emitting element, and a side surface angle of the first protrusion differs from a side surface angle of the planarization layer, which is exposed through the pixel contact hole. Thereby, the cathode electrode and an auxiliary connection electrode may be electrically connected to each other without a separate partition, which may simplify the structure and the manufacturing process of the organic light-emitting display device.
