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: An organic light-emitting display device is provided. The device can include a display area having an organic light-emitting element on a lower substrate; a bezel area surrounding the display area; a transparent encapsulation unit having first and second encapsulation layers, and a first particle cover; and a first buffer layer. The first encapsulation layer can cover the display area and the bezel area. The first particle cover layer can cover the display area and a portion of the bezel area adjacent to the display area. The first buffer layer, apart from the first particle cover layer, can cover another portion of the bezel area. The second encapsulation layer, which covers the first particle cover layer and the first buffer layer, contacts the first encapsulation layer at a contact surface between the first particle cover layer and the first buffer layer.
