Abstract
Discussed is a display device including a base portion; assembly electrodes that extend in one direction and are disposed on the base portion at predetermined intervals; a dielectric layer deposited on the base portion to cover the assembly electrodes; a first wiring electrode that extends in the same direction as the assembly electrodes and is disposed on the dielectric layer so as not to overlap the assembly electrodes; a partition wall portion deposited on the dielectric layer while arranging cells at predetermined intervals to overlap the assembly electrodes and the first wiring electrode along an extension direction of the assembly electrodes; and semiconductor light-emitting elements seated in the cells, respectively, wherein a solder layer electrically connecting a semiconductor light-emitting element seated in a cell and the first wiring electrode overlapping the cell is filled in the cell from among the plurality semiconductor light emitting elements and the cells.
