Light emitting device

摘要

A light emitting structure including a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer. A first electrode is electrically coupled to the first conductive semiconductor layer. A current blocking layer is provided adjacent to the light emitting structure, and includes a top surface disposed in the first conductive semiconductor layer by passing through the active layer. A first metal layer is provided over the current blocking layer and contacts the first conductive semiconductor layer, and a reflective electrode is electrically coupled to the second conductive semiconductor layer.
