PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting device superior in controllability of chromaticity.SOLUTION: A semiconductor light-emitting device according to an embodiment comprises: a light-emitting element having a light-emitting layer; a first transparent material provided on the light-emitting element; a phosphor dispersed in the first transparent material, which emits light different, in wavelength, from light emitted by the light-emitting layer; and a second transparent material having a first transparent part surrounded by the first transparent material in a region on the light-emitting element, and a second transparent part provided on the first transparent material and the first transparent part. The second transparent part is formed over the first transparent part and has an inclined part inclined with respect to a first direction perpendicular to the light-emitting layer.SELECTED DRAWING: Figure 3 【課題】色度の制御性に優れた半導体発光装置を提供する。【解決手段】実施形態によれば、半導体発光装置は、発光層を有する発光素子と、前記発光素子の上に設けられた第１透明体と、前記第１透明体中に分散され前記発光層から放射される光とは異なる波長の光を発光する蛍光体と、前記発光素子の上の領域で前記第１透明体に囲まれた第１透明部と、前記第１透明体上および前記第１透明部上に設けられた第２透明部と、を有する第２透明体と、を備える。前記第２透明部は、前記第１透明部の上に形成され、前記発光層に対して垂直な第１方向に対して傾斜した傾斜部を有する。【選択図】図３
