PROBLEM TO BE SOLVED: To provide a light emitting device.SOLUTION: A light emitting device includes a light emitting layer, an opening part, a recessed part, and an electrode. The light emitting layer includes a first semiconductor layer, a second semiconductor layer, and the light emitting layer formed between the first semiconductor layer and the second semiconductor. The first semiconductor layer includes a first surface, a first portion connected to the first surface, and a second portion connected to the first portion. The opening part penetrates from an upper part surface to the first portion of the first semiconductor layer. The recessed part is connected to the opening part, and penetrates the second semiconductor layer, the light emitting layer, and the second portion of the first semiconductor layer, and further, its bottom part has a width wider than the opening part so that a second surface is exposed from the side opposite to the first surface of the first semiconductor layer. The electrode is arranged in the recessed part, to correspond to the opening part. 【課題】発光装置を提供する。【解決手段】発光装置は、発光層と開口部と凹部と電極を含む。発光層は、第一半導体層と第二半導体層および第一半導体層と第二半導体の間に形成される発光層を有し、第一半導体層は、第一表面と第一表面に連結する第一部分と第一部分に連結する第二部分を含み、開口部は、上部表面から第一半導体層の第一部分を突き抜き、凹部は、開口部に連結し、第二半導体層と発光層と第一半導体層の第二部分を突き抜き、且つその底部が第一半導体層の第一表面の反対側に第二表面を露出するよう開口部より広い幅を有し、電極は、凹部に配置され、開口部と対応する。【選択図】図１H
