Abstract: The present invention relates to a display device having a structure in which an assembly substrate on which self-assembly has taken place can be used as a final substrate, and a method for manufacturing same. According to an embodiment of the present invention, first-conductive-type electrodes of vertical-type semiconductor light-emitting elements can be connected to seed metal, which is used as a wiring electrode, via a solder part, and thus there is the effect of directly using, as a final substrate, an assembly substrate on which the vertical-type semiconductor light-emitting elements are self-assembled, without an additional transfer process.
