Abstract
A light-emitting device discloses a light emitting structure layer including an active layer between first and second conductive semiconductor layers, a first electrode electrically connected to the first conductive semiconductor layer, a contact layer disposed under the second conductive semiconductor layer, a reflective layer disposed under the contact layer, a capping layer disposed under the reflective layer, and a conductive supporting member disposed under the capping layer. The reflective layer comprises a thickness that is greater than the thickness of the second conductive semiconductor layer and 90 or more times greater than the thickness of the contact layer.
