Abstract
A light emitting diode having improved light efficiency and enhanced reflectivity of a device by forming an insulating reflective part on a reflective electrode formed on the upper surface of a mesa. A mesa exposing part is formed on the outer periphery and/or in the interior region of the reflective electrode to expose a predetermined area of the upper surface of the mesa such that reflection at the mesa exposing part is performed by the insulating reflective part.
