Abstract: A display device including a substrate, a plurality of first data lines and a plurality of second data lines. The substrate includes a display area, in which a hole is formed, and a hole edge area surrounding the hole. The plurality of first data lines are disposed on the substrate, extend in a first direction in the display area, are arranged in a second direction orthogonal to the first direction, and bypass the hole along the hole edge area. The plurality of second data lines are disposed on the substrate, extend in the first direction in the display area, are arranged adjacent to the plurality of first data lines, and bypass the hole along hole edge area. In the hole edge area, each of the plurality of first data lines and the plurality of second data lines are disposed on three layers different from each other.

Abstract: 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.
