Abstract: A display device includes a substrate comprising a plurality of pixel areas and a non-pixel area surrounding each of the plurality of pixel areas. The non-pixel area includes a plurality of first areas and a second area surrounding the plurality of first areas. A functional layer is disposed on the substrate and includes a plurality of first holes defined through the functional layer and overlapping the plurality of first areas. An element layer is disposed on the functional layer. A pixel definition layer is disposed on the element layer and overlaps the non-pixel area. The pixel definition layer includes pixel openings defined therethrough. The pixel openings overlap the plurality of pixel areas. A plurality of light emitting elements is disposed on the element layer and is disposed in the pixel openings.
