Abstract: An organic light-emitting display device includes an anti-peeling pattern. An organic light-emitting element including a pixel electrode, an organic light-emitting layer, and a common electrode is disposed on a substrate. A bank layer is disposed on the pixel electrode so as to expose at least a portion of the pixel electrode. The anti-peeling pattern having at least one delta-shaped space is disposed on the bank layer. The anti-peeling pattern, disposed on the bank layer, minimizes peeling of the encapsulation layer that can be caused by either compressive or tensile stress generated by bending in a flexing environment in which the organic light-emitting display device is used.

Abstract: A touch display device includes a touch planarization film. The touch planarization film may be disposed on an inclined portion of an encapsulation layer in a non-active area of a display panel, and a touch routing line may be disposed on the planarized area of the touch planarization film, so that it is possible to reduce parasitic capacitance between the touch routing line and a display signal line located under the encapsulation layer without increasing dimensions of the non-active area. Therefore, it is possible to easily adjust a width of the touch routing line and reduce the parasitic capacitance deviation between the touch routing lines, thereby improving the performance of the touch sensing.
