Abstract
A light emitting device is provided a transmissive substrate; a first pattern portion including a protrusions; a second pattern portion including a concaves having a width smaller than a width of each protrusion; a light emitting structure including a first conductive semiconductor layer, a second conductive semiconductor layer and an active layer, under the transmissive substrate; a first electrode under the first conductive semiconductor layer; a reflective electrode layer under the second conductive semiconductor layer; a second electrode under the reflective electrode layer; a first connection electrode under the first electrode; a second connection electrode under the second electrode; and an insulating support member around the first electrode and the first connection electrode and around the second electrode and the second connection electrode. A transmissive resin layer is on the transmissive substrate and an insulating layer is between the insulating support member and the reflective electrode layer.
