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: Disclosed are a color filter array having a touch sensor and a display panel having the same. The color filter array may comprise: a plurality of color filters arranged in first and second directions on a substrate; a touch block electrode disposed on the color filters to sense a user touch position; a black matrix disposed on the touch block electrode between the color filters; and a touch-sensing line which is disposed in any one of the first and second directions and at least one of which is connected to the touch block electrode. Thereby, when the color filter array is applied to a bending-type or folding-type display device, generation of cracks in the touch sensing line is reduced or minimized.
