Abstract: A display device may include a first electrode, a second electrode, an emission layer, an intervening layer, and a first encapsulation layer. The second electrode may overlap the first electrode. The emission layer may be disposed between the first electrode and the second electrode, may overlap the first electrode, and may include a light emitting material. The intervening layer may directly contact the second electrode, may be spaced from each of the first electrode and the emission layer, and may include a fluorine compound. A first section of the first encapsulation layer may overlap the emission layer. The intervening layer may be positioned between the second electrode and a second section of the first encapsulation layer.

Abstract: An organic light emitting display panel and associated methods, the panel including a substrate; an organic light emitting diode (OLED) on the substrate; and an encapsulation member to separate the OLED from an external environment, wherein the OLED includes a first electrode on the substrate; a pixel defining layer exposing the first electrode and including a flat planar surface and an inclined planar surface extending from the flat planar surface such that the inclined planar surface overlaps an edge of the first electrode; an organic layer, the organic layer including a first region on the first electrode and a second region on the inclined planar surface; and a second electrode on the organic layer, and wherein, in the second region, a thickness of the organic layer is decreased along a direction extending away from the first region.
