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.
