Zusammenfassung: | To provide a light-emitting device that can improve light extraction efficiency.SOLUTION: A light-emitting device has: a first electrode; a second electrode that is arranged opposite to the first electrode and has light transmissivity; a laminate that is provided between the first electrode and the second electrode, and has a tapered shape whose width is increased toward a side of the second electrode from a side of the first electrode; and a first metal layer that is provided on a side face of the tapered part. The laminate has a first semiconductor layer having a first conductivity type, a second semiconductor layer provided between the first semiconductor layer and the second electrode and having a second conductivity type different from the first conductivity type, and a luminous layer provided between the first semiconductor layer and the second semiconductor layer. Light generated in the luminous layer is emitted from a side of the second electrode. The first metal layer and the first electrode are separated and electrically insulated from each other.SELECTED DRAWING: Figure 1
【課題】光の取り出し効率を向上できる発光装置を提供する。【解決手段】第1電極と、前記第1電極と対向配置され、透光性を有する第2電極と、前記第1電極と前記第2電極との間に設けられ、前記第1電極側から前記第2電極側に向かうにつれて幅が大きくなるテーパー形状を有するテーパー部を有する積層体と、前記テーパー部の側面に設けられた第1金属層と、を有し、前記積層体は、第1導電型を有する第1半導体層と、前記第1半導体層と前記第2電極との間に設けられ、前記第1導電型と異なる第2導電型を有する第2半導体層と、前記第1半導体層と前記第2半導体層との間に設けられた発光層と、を有し、前記発光層で発生した光は、前記第2電極側から出射され、前記第1金属層および前記第1電極は、互いに離隔されて、電気的に絶縁されている、発光装置。【選択図】図1 |
