Abstract
An organic light-emitting display device includes a first pixel electrode, a second pixel electrode, a pixel-defining layer disposed on the first pixel electrode and the second pixel electrode and exposing at least portions of the first pixel electrode and the second pixel electrode, a first stack disposed on the exposed portion of the first pixel electrode, a first protective layer, a second stack disposed on the exposed portion of the second pixel electrode, and a first inorganic conductive layer. The first stack includes a first intermediate layer including an emission layer and a first opposite electrode on the first intermediate layer. The first protective layer is disposed on the first stack. The second stack includes a second intermediate layer including an emission layer and a second opposite electrode on the second intermediate layer. The first inorganic conductive layer is disposed between the second pixel electrode and the second stack.
