Discussed is a display device, including a substrate including a dielectric layer, a plurality of semiconductor light-emitting devices respectively accommodated on the substrate, and a first electrode provided with a plurality of electrode lines arranged on a bottom of the substrate. Each of the first electrode includes a pair of electrode lines spaced from each other on an upper surface of the dielectric layer among the plurality of electrode lines. Each semiconductor light-emitting device is disposed on the pair of electrode lines, and the pair of electrode lines have the same electrical pole.
