Abstract
A light-emitting device includes a light-emitting laminated structure, an electrode structure that is disposed on the light-emitting laminated structure, an insulation layer that is disposed on the light-emitting laminated structure, and a blocking layer structure that is interposed between the electrode structure and the insulation layer. The light-emitting laminated structure includes a first type semiconductor layer, a second type semiconductor layer, and an active layer that is interposed between the first type semiconductor layer and the second type semiconductor layer and is configured to emit light. The blocking layer structure has a first section and a second section that forms a continuous structure with the first section. The first section is interposed between a side wall of the electrode structure and the insulation layer, and the second section is interposed between the insulation layer and the light-emitting laminated structure.
