Abstract: A display device includes a substrate including a central area and a corner area, the corner area extending in a direction away from the central area and including a plurality of extension areas including distal portions spaced apart from each other, a plurality of display elements arranged on a front surface of the substrate and arranged in the central area and the plurality of extension areas, and a first organic filler between adjacent extension areas among the plurality of extension areas. The first organic filler is between distal portions of the adjacent extension areas, and the adjacent extension areas and the first organic filler are disposed on a curved surface of the substrate that is different from a surface of the substrate on which the central area is disposed.
