Abstract
A thin film transistor is disposed on a substrate. A via insulating layer having a via hole covers the thin film transistor. A pixel electrode is disposed on the via insulating layer and electrically connected to the thin film transistor through the via hole. A first protection layer surrounds the pixel electrode. A pixel-defining layer covers an edge region of the pixel electrode and at least a portion of the first protection layer. The pixel-defining layer includes an opening through which an upper surface of the pixel electrode is exposed. An opposite electrode faces the pixel electrode. An intermediate layer is disposed between the pixel electrode and the opposite electrode.
