Abstract
The present invention may be applied to display device-related technical fields and relates to a display device using a semiconductor light-emitting element, such as a micro light-emitting diode (LED), and a manufacturing method therefor. The present invention, according to one embodiment, may comprise: a substrate; a stepped film positioned on at least some pixel regions, among a plurality of individual pixel regions positioned on the substrate; an assembly electrode positioned on the substrate or the stepped film; an insulation layer positioned on the assembly electrode; a partition wall positioned on the insulation layer and defining an assembly groove having mounted therein a semiconductor light-emitting element forming the individual pixel; the semiconductor light-emitting element mounted in an assembly surface of the assembly groove; and a lighting electrode electrically connected to the semiconductor light-emitting element.
