Abstract: The present invention relates to a device and method for self-assembling semiconductor light-emitting diodes. Particularly, a method for manufacturing a display device according to the present invention includes: feeding a substrate to an assembly site and putting semiconductor light-emitting diodes having a magnetic material into a fluid chamber; applying a magnetic force to the semiconductor light-emitting diodes so that the semiconductor light-emitting diodes move in one direction within the fluid chamber; and guiding the semiconductor light-emitting diodes to preset positions on the substrate by applying an electric field, so that the semiconductor light-emitting diodes are mounted at the preset positions while in the process of being moved.
