Abstract
A display device includes pixel electrodes spaced apart from one another on a substrate; light-emitting elements disposed on the pixel electrodes; a common electrode layer disposed on the light-emitting elements; and an undoped semiconductor layer disposed on the common electrode layer. The display device includes nanostructures disposed in the common electrode layer and spaced apart from one another, and the common electrode layer includes a first common electrode layer disposed between the undoped semiconductor layer and the nanostructures, and a second common electrode layer disposed between adjacent nanostructures and disposed between the light-emitting elements and the nanostructures.
