1. A display device comprising:
a base portion;
a plurality of assembly electrodes extending along a first direction and formed at predetermined intervals on the base portion;
a first dielectric layer disposed on the base portion to cover the assembly electrodes;
a plurality of seed metals formed on the first dielectric layer and extending along the first direction;
a plurality of barrier ribs formed to cover at least a portion of a top of each of the plurality of seed metals, wherein a plurality of cells are formed on the first dielectric layer at predetermined intervals between the plurality of barrier ribs and wherein each cell overlaps at least a portion of a corresponding assembly electrode of the plurality of assembly electrodes;
a plurality of semiconductor light emitting diodes correspondingly positioned in the plurality of cells; and
a plurality of solder portions each positioned at at least a portion of a bottom surface of a corresponding cell to connect a corresponding semiconductor light emitting diode to a corresponding seed metal.
