Abstract: A display device includes anode electrodes in a display area, an inorganic insulating layer in the display area and partially on the anode electrode, a bank structure on the inorganic insulating layer, with openings overlapping the anode electrodes, light emitting layers on the anode electrodes and in the openings, cathode electrodes on the light emitting layers and in the openings, a first power line in a non-display area, and a conductive layer including an oxide semiconductor. A portion of the conductive layer in the non-display area is between the first power line and the display area. The bank structure is on the conductive layer in the non-display area with hole patterns defined further through the conductive layer, the bank structure includes first and second bank layers including different metal materials, respectively, and a portion of the first bank layer is directly on the conductive layer in the non-display area.
