Summary:A light-emitting device according to one embodiment of the present invention may comprise: a first semiconductor layer; a light-emitting layer disposed on the first semiconductor layer; a second semiconductor layer disposed on the light-emitting layer; an electrode layer disposed on the second semiconductor layer; and an insulation coating covering the side surfaces of the first semiconductor layer, the light-emitting layer and the second semiconductor layer, the insulation coating covering from one end part of the light-emitting device on which the electrode layer is disposed to one part of the electrode layer. The electrode layer may comprise: a first surface adjacent to the second semiconductor layer; a second surface facing the first surface and having a smaller width than the width of the first surface; and side surfaces connecting the first surface and the second surface and having an inclination corresponding to an angle in the range of 75° to 90° with respect to the first surface. Un mode de réalisation de la présente invention concerne un dispositif électroluminescent pouvant comprendre : une première couche semi-conductrice ; une couche électroluminescente disposée sur la première couche semi-conductrice ; une seconde couche semi-conductrice disposée sur la couche électroluminescente ; une couche d'électrode disposée sur la seconde couche semi-conductrice ; et un revêtement isolant recouvrant les surfaces latérales de la première couche semi-conductrice, la couche électroluminescente et la seconde couche semi-conductrice, le revêtement d'isolation recouvrant une partie d'extrémité du dispositif électroluminescent sur lequel la couche d'électrode est disposée sur une partie de la couche d'électrode. La couche d'électrode peut comprendre : une première surface adjacente à la seconde couche semi-conductrice ; une seconde surface faisant face à la première surface et ayant une largeur inférieure à la largeur de la première surface ; et des surfaces latérales reliant la première surface et la seconde surface et ayant une inclinaison correspondant à un angle dans la plage de 75° à 90° par rapport à la première surface. 본 발명의 일 실시예에 의한 발광 소자는, 제1 반도체층; 상기 제1 반도체층 상에 배치된 발광층; 상기 발광층 상에 배치된 제2 반도체층; 상기 제2 반도체층 상에 배치된 전극층; 및 상기 제1 반도체층, 상기 발광층 및 상기 제2 반도체층의 측면을 감싸며, 상기 전극층이 배치된 발광 소자의 일 단부에서 상기 전극층의 일 부분을 감싸는 절연 피막을 포함할 수 있다. 상기 전극층은, 상기 제2 반도체층에 인접한 제1 면; 상기 제1 면과 대향하며, 상기 제1 면의 폭보다 작은 폭을 가지는 제2 면; 및 상기 제1 면과 상기 제2 면을 연결하며, 상기 제1 면에 대하여 75° 내지 90° 범위의 각도에 대응하는 경사를 가지는 측면을 포함할 수 있다.
