1. A display device comprising:
pixel electrodes disposed on a substrate;
light-emitting elements, each of the pixel electrodes having at least two corresponding light-emitting elements among the light-emitting elements disposed thereon;
a planarization layer disposed on and spacing the pixel electrodes apart from one another, the planarization layer filling spaces between the light-emitting elements and spaces between the pixel electrodes; and
a common electrode disposed on the planarization layer and the light-emitting elements, wherein
each of the at least two corresponding light-emitting elements is arranged perpendicular to a top face of a corresponding pixel electrode among the pixel electrodes;
at least one of the pixel electrodes includes a protrusion protruding toward and spaced apart from an adjacent one of the pixel electrodes, and
one of the at least two corresponding light-emitting elements disposed on the at least one pixel electrode overlaps the protrusion in a plan view.
