To provide a light-emitting device in which a step of brilliance is less between regions of different brilliance, and visibility is high.SOLUTION: A light-emitting device has a mounting board 11, and multiple light-emitting structures 10A, 10B juxtaposed on the mounting board and arranged in a first arrangement direction and a second arrangement direction perpendicular to the first arrangement direction, where each of the multiple light-emitting structures includes a semiconductor light-emitting element 12, and a wavelength conversion member 17 formed on a top face of the semiconductor light-emitting element. In at least one of the light-emitting structures located at both ends in the first arrangement direction, lateral faces of the semiconductor light-emitting element and the wavelength conversion member facing the light-emitting structure adjoining in the first arrangement direction are coated with a coating member 19, the lateral face of the semiconductor light-emitting element at an end side in the first arrangement direction is coated with the coating member, and the lateral face of the wavelength conversion member is exposed.SELECTED DRAWING: Figure 1B 【課題】輝度の異なる領域間において輝度の段差が少なく視認性が高い発光装置を提供する。【解決手段】搭載基板１１と、搭載基板上に並置されて第１の配列方向及び第１の配列方向に垂直な方向である第２の配列方向に配列された複数の発光構造体１０Ａ、１０Ｂを有し、複数の発光構造体の各々は、半導体発光素子１２と、半導体発光素子の上面に形成された波長変換部材１７と、を含み、第１の配列方向の両端に位置する発光構造体のうち少なくとも１つの発光構造体は、第１の配列方向において隣接する発光構造体に面する半導体発光素子及び波長変換部材の側面は被覆部材１９によって被覆され、第１の配列方向の端部側の半導体発光素子の側面は被覆部材によって被覆されるとともに波長変換部材の側面が露出していることを特徴とする。【選択図】図１Ｂ
