Abstract: A display device is disclosed that includes an auxiliary power line, a first inorganic insulating layer, a second inorganic insulating layer, a pixel defining layer, and a common electrode. The auxiliary power line is disposed in a display area on a substrate. The first inorganic insulating layer is disposed on the auxiliary power line and defines a first opening extending to at least part of an upper surface of the auxiliary power line. The second inorganic insulating layer is disposed on the first inorganic insulating layer and defines a second opening connected to the first opening. The pixel defining layer is disposed on the second inorganic insulating layer and defines a pixel contact hole connected to the first and second openings. An end of the pixel defining layer includes a protrusion protruding toward a center of the pixel contact hole. The common electrode disposed on the pixel defining layer and electrically connected to the auxiliary power line.
