Abstract

본 개시는 기판; 기판의 상면에 형성되며 전자와 정공의 재결합에 의해 빛을 방출하는 활성층을 포함하는 복수의 반도체층; 기판의 하면에 형성되며 기판을 투과한 빛을 반사시키는 금속층; 기판의 하면과 금속층 사이에 위치되며 SiO2로 형성된 제1 물질층; 제1 물질층과 금속층 사이에 위치되며 TiO2로 형성된 제2 물질층; 및 제2 물질층과 금속층 사이에 위치되며 SiO2로 형성된 제3 물질층;을 포함하며, 제1,2,3 물질층은 기판의 하면에서 하방으로 차례로 적층되고 서로 다른 두께를 갖는 것을 특징으로 하는 반도체 발광소자를 제공한다.
