Abstract
The present disclosure provides a novel form of a display device which enables semiconductor light emitting elements having a vertical structure to be assembled onto a substrate and then wiring process to be performed stably without any change to the position of the elements during post-processing. The display device according to one embodiment of the present disclosure comprises: a substrate; a pair of assembly electrodes positioned on the substrate; a dielectric layer positioned on the assembly electrodes; a wiring electrode positioned on the dielectric layer and comprising a base electrode part and a low melting point junction; a partition wall which overlaps with a portion of the wiring electrode, is positioned on the dielectric layer, and defines an assembly groove to which a semiconductor light emitting element is assembled; and the vertical semiconductor light emitting element which is assembled in the assembly groove and is electrically connected to the low melting point junction of the wiring electrode, wherein the low melting point junction has a flow stop angle for controlling the thermal flow characteristic of the junction.
