Abstract: A display device includes a planarization layer on a substrate, a pixel with an organic electroluminescence element on the planarization layer, a sealing layer covering the pixel, a terminal electrode arranged at an edge of the substrate, and a first wiring arranged over the sealing layer and electrically connected to the terminal electrode. The planarization layer has an outer edge that forms a step over the substrate between the pixel and the terminal electrode. The first wiring extends from above the sealing layer to intersect with the step. In a plan view, the step has a first protrusion of the planarization layer protruding in a direction of the terminal electrode, a second protrusion adjacent to the first protrusion and protruding in a direction of the terminal electrode, and an intermediate region between the first protrusion and the second protrusion.
