Abstract

Disclosed in the present specification are a micro LED display device in which an assembly electrode capable of forming a non-uniform electric field is assembled in a provided assembly hole, and a manufacturing method therefor. The display device according to one embodiment of the present invention comprises: a substrate; a first assembly electrode and a second assembly electrode arranged to be spaced apart on the substrate; an insulating layer deposited on top of the first assembly electrode and the second assembly electrode; an assembly hole defining a pixel area formed on the insulating layer; a semiconductor light-emitting element assembled in the assembly hole; and a wiring electrode electrically connected to the semiconductor light-emitting element, wherein the first assembly electrode and the second assembly electrode have a pattern for generating non-uniform electric field in the assembly hole by means of applied voltage, and the semiconductor light-emitting element is assembled, on the basis of the non-uniform electric field, at a specific location in the assembly hole after moving in a specific direction.
