LIGHT-EMITTING ELEMENT AND A PRODUCTION METHOD THEREFOR

摘要

According to an embodiment of this invention, a light-emitting element comprises: a supporting substrate; a planarization layer on the supporting substrate; a wafer-bonding layer on the planarization layer; a current-spreading layer on the wafer-bonding layer; a second electrically conductive semiconductor layer on the current-spreading layer; an active layer on the second electrically conductive semiconductor layer; a first electrically conductive semiconductor layer on the active layer; a first electrode layer on the first electrically conductive semiconductor layer; and a second electrode layer on the current-spreading layer.
