Abstract
The present invention relates to a display device and, particularly, to a display device using a semiconductor light emitting element. The display device according to the present invention comprises a plurality of semiconductor light emitting elements mounted on a substrate, wherein at least one of the semiconductor light emitting elements comprises: a first conductive electrode and a second conductive electrode; a first conductive semiconductor layer in which the first conductive electrode is disposed; a second conductive semiconductor layer which overlaps the first conductive semiconductor layer and in which the second conductive electrode is disposed; a first passivation layer formed to cover outer surfaces of the first conductive semiconductor layer and the second conductive semiconductor layer; and a second passivation layer formed to cover the first passivation layer and formed such that at least a portion thereof varies in thickness.
