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: This present disclosure discloses a display device. The display device may include a bending area and a non-bending area. A structure for improving durability may be included in the bending area. The display device may include a base layer having one or more first regions that can be folded along a predetermined axis, and a second region adjacent to the first regions; and thin-film transistors, organic light-emitting elements and functional layers stacked in the second region of the base layer. The thin-film transistors, the organic light-emitting elements and the functional layers stacked in the second regions are not disposed in the first regions. Instead, the space otherwise occupied by the elements is filled with the filling layer.
