A display device includes a substrate having a first area, a second area, and a bending area disposed between the first area and the second area. An inner wiring is disposed in the first area. An outer wiring is disposed in the second area. An interlayer insulating layer covers the inner wiring and the outer wiring, and includes a first contact hole. A conductive layer is disposed on the interlayer insulating layer, and is connected to the inner wiring or the outer wiring through the first contact hole. An inorganic protective layer covers at least a portion of the conductive layer and includes an inorganic insulating material.
