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: The present disclosure relates to a display device for improving productivity. The display device having a touch sensor is configured such that the total thickness of at least one inorganic insulation layer disposed on the region above each of dams is different from the total thickness of the at least one inorganic insulation layer disposed on a trench region between the dams. Thus, a photoresist for forming a routing line is formed so as to have a uniform thickness on the region above each of the dams and the trench region between the dams, and thus productivity is improved.

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: A touch display device in which routing lines are formed to have the same resistance value. Routing lines connected to touch electrodes in a non-active area and display signal links electrically connected to a light-emitting element are formed in different shapes from each other, and the lengths of at least one of zigzag patterns of the routing lines disposed in the non-active area and single-line regions are formed differently.
