Abstract: A display device includes a first electrode and a second electrode disposed on a substrate and spaced part from each other in a first direction. A light emitting element is disposed between the first electrode and the second electrode. A third electrode is disposed on the first electrode and electrically contacts an end portion of the light emitting element. A fourth electrode is disposed on the second electrode and electrically contacts another end portion of the light emitting element. A side of the third electrode and a side of the first electrode are located on a first virtual line substantially perpendicular to the substrate. A side of the fourth electrode facing the side of the third electrode and the side of the second electrode are located on a second virtual line substantially perpendicular to the substrate.
