A display device includes a substrate on which pixels are defined, a pixel electrode disposed for each of the pixels on the substrate, a pixel defining layer disposed along a boundary of the pixels, the pixel defining layer including an opening exposing the pixel electrode, a light emitting layer disposed on the pixel electrode in the opening of the pixel defining layer, and a hole injection layer disposed between the pixel electrode and the light emitting layer. The hole injection layer includes an adhesion promoting layer disposed on the pixel electrode. |
