Abstract: A display device includes a substrate having a display area and a non-display area; a first transistor that is disposed on the substrate and that overlaps the display area; a first pixel defining layer disposed on the first transistor; a first emission layer disposed in the first pixel defining layer; a second pixel defining layer that is disposed on the substrate and that overlaps the non-display area; a second emission layer disposed in the second pixel defining layer; a second electrode disposed on the first emission layer and the second emission layer; and an encapsulation organic layer disposed on the second electrode, wherein the encapsulation organic layer overlaps the first pixel defining layer and the second pixel defining layer, and an end of the encapsulation organic layer is disposed inside the second pixel defining layer.
