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 comprises a substrate including a first sub pixel and a second sub pixel disposed in a first direction; a thin film transistor disposed on the substrate and corresponds to each of the first sub pixel and the second sub pixel; a planarization layer on the thin film transistor; an organic light emitting diode which is disposed on the planarization layer so as to correspond to each of the first sub pixel and the second sub pixel and has an anode, an organic emission layer, and a cathode; an auxiliary electrode between the first sub pixel and the second sub pixel; and a partition which is disposed on the auxiliary electrode so as to at least partially overlap the auxiliary electrode. The auxiliary electrode protrudes toward the first sub pixel and the second sub pixel from corners of the partition in plan view.

Abstract: The present disclosure relates to a flexible display device including: a substrate over which a thin film transistor is disposed, an intermediate layer disposed to cover the thin film transistor, a first electrode located on the intermediate layer and connected to the thin film transistor, a bank located on the intermediate layer and the first electrode and defining a first region exposing a part of the intermediate layer, a second region exposing a part of the first electrode, and a third region excluding the first and second regions, a first structure located in the first region defined by the bank and tapered toward the substrate, an organic light emitting layer located on the first electrode exposed in the second region, and a second electrode disposed on the organic light emitting layer. Both lateral surfaces of an inverse-tapered structure are disposed to contact the bank, and as a result, corresponding adhesion can be improved, and peeling defects can be reduced or corrected.
