Abstract
The present specification provides a micro LED display device which minimizes a short-circuit fault by using a semiconductor light emitting element including multiple passivation layers formed therein, and a manufacturing method thereof. In a display device using a plurality of semiconductor light emitting elements according to one embodiment of the present invention, at least one of the semiconductor light emitting elements comprises: a first conductive semiconductor layer; a second conductive semiconductor layer; an active layer; a first conductive electrode; a second conductive electrode; and a first passivation layer and a second passivation layer successively disposed to surround the lateral surfaces of the first conductive semiconductor layer and the second conductive semiconductor layer, wherein the second passivation layer is positioned in a region excluding parts in contact with a first electrode and a second electrode, on the first conductive electrode and the second conductive electrode.
