    Abstract: An organic light-emitting display device includes: a substrate; a pixel electrode on the substrate; a pixel defining layer having a first opening exposing a center portion of the pixel electrode; a barrier layer on the pixel defining layer; an intermediate layer including a first common layer, a first emissive layer, and a second common layer sequentially arranged on the pixel electrode, the pixel defining layer, and the barrier layer; and a first opposite electrode covering the intermediate layer. The barrier layer has a second opening that is larger than the first opening and has an undercut structure.

    Abstract: A display device including a first pixel electrode and a second pixel electrode disposed adjacent to each other on a substrate; a pixel defining layer including a first opening corresponding to the first pixel electrode, a second opening corresponding to the second pixel electrode, and a first convex portion arranged adjacent to the first opening; a first intermediate layer arranged on the first pixel electrode to correspond to the first opening and including a first emission layer; and a first conductive inorganic layer arranged on the first intermediate layer to correspond to the first opening. At least one end of the first conductive inorganic layer extends beyond an end of the first intermediate layer and is disposed on the pixel defining layer between the first opening and the second opening.
