Light emitting device with a stepped structure
A light emitting device including a first semiconductor layer, a light emitting layer, a second semiconductor layer, a first electrode, and a second electrode is provided. The light emitting layer is deposited between the first and the second semiconductor layers. The first semiconductor layer, the light emitting layer and the second semiconductor layer form a stepped structure including a first electrode connection surface, a second electrode connection surface, and a connection portion. The first electrode connection surface is located on the first semiconductor layer. The second electrode connection surface is located on the second semiconductor layer. The connection portion connects the first and the second electrode connection surfaces. The connection portion includes a first surface, a second surface, and a third surface. A first corner s formed between the first and the second surfaces. A second corner is formed between the second and the third surfaces.
