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.

An organic light-emitting display device comprising:
- 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, the barrier layer having a second opening that is larger than the first opening and having an undercut structure;
- an intermediate layer comprising 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,
- wherein portions of the first opposite electrode on the pixel electrode, the pixel defining layer, and the barrier layer are connected to each other,
- wherein portions of the first common layer are disconnected from each other at a boundary between the pixel defining layer and the barrier layer.
An organic light-emitting display device comprising:
- a substrate;
- a pixel electrode on the substrate;
- a pixel defining layer having a first opening exposing a center portion of the pixel electrode, the first opening having an edge arranged within a periphery of the pixel electrode and having an undercut structure;
- an intermediate layer comprising a first common layer, a first emissive layer, and a second common layer sequentially arranged on the pixel electrode and the pixel defining layer;
- and
- a first opposite electrode covering the intermediate layer,
- wherein portions of the first common layer are disconnected from each other at a boundary between the pixel defining layer and the pixel electrode.
