Light emitting device, light emitting device package, and lighting apparatus including the package

Abstract

Embodiments provide a light emitting device including a substrate, a light emitting structure including a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer, disposed under the substrate, a reflective layer disposed under the second conductive semiconductor layer, the reflective layer having at least one first through-hole formed in a first direction, the first direction being a thickness direction of the light emitting structure, a contact layer embedded in at least one second through-hole penetrating the reflective layer, the second conductive semiconductor layer, and the active layer so as to be connected to the first conductive semiconductor layer, and an insulation layer disposed between the contact layer and each of the reflective layer, the second conductive semiconductor layer, and the active layer, the insulation layer being embedded in the first through-hole.
