A display device includes a plurality of semiconductor light emitting diodes, first and second electrodes respectively extending from the plurality of semiconductor light emitting diodes to supply an electrical signal to the plurality of semiconductor light emitting diodes, a plurality of pair electrodes disposed on a substrate and having a first electrode and a second electrode, a dielectric layer disposed on the plurality of pair electrodes, and a chemical bond layer disposed between the dielectric layer and the plurality of semiconductor light emitting diodes and forming a covalent bond with the dielectric layer and each of the plurality of semiconductor light emitting diodes. The chemical bond layer bonds the semiconductor light emitting diodes to the dielectric layer when a voltage applied to the plurality of pair electrodes is cut off after the plurality of semiconductor light emitting diodes are assembled on the dielectric layer.
