Abstract: A display device includes a substrate on which a plurality of subpixels is defined, and a plurality of light-emitting elements respectively disposed in the plurality of subpixels. Each of the plurality of light-emitting elements includes a first semiconductor layer, a light-emitting layer on the first semiconductor layer, and a second semiconductor layer on the light-emitting layer. The first semiconductor layer includes a first part having a flat top surface, and a second part protruding upward from the first part and being in direct contact with a bottom surface of the light-emitting layer. An area of a top surface of the second semiconductor layer is larger than an area of a bottom surface of the second semiconductor layer.
