Abstract: A display apparatus includes a substrate, a pixel defining layer, a spacer, an auxiliary electrode, and an organic light emitting diode. The substrate includes a light emitting area and a non-light emitting area adjacent to the light emitting area. The pixel defining layer is disposed on the non-light emitting area of the substrate. The spacer is disposed on the pixel defining layer. The auxiliary electrode is disposed on the spacer. The organic light emitting diode is disposed on the substrate, and at least a portion thereof is disposed in the light emitting area. The organic light emitting diode includes a pixel electrode, an intermediate layer disposed on the pixel electrode and including an organic light emitting layer, and an opposite electrode disposed on the intermediate layer and electrically connected to the auxiliary electrode.
