Patent ID: 8222659

Claim:
A semiconductor light-emitting device comprising: (A) a light-emitting portion obtained by laminating in sequence a first compound semiconductor layer having a first conductivity type, an active layer, and a second compound semiconductor layer having a second conductivity type that is different from the first conductivity type; (B) a first electrode electrically connected to the first compound semiconductor layer; (C) a transparent conductive material layer formed on the second compound semiconductor layer; (D) an insulating layer composed of a transparent insulating material and having an opening, the insulating layer being formed on the transparent conductive material layer; and (E) a second electrode that reflects light from the light-emitting portion, the second electrode being formed on the transparent conductive material layer exposed at a bottom of the opening and on the insulating layer in a continuous manner, wherein, assuming that an area of the active layer constituting the light-emitting portion is S 1 , an area of the transparent conductive material layer is S 2 , an area of the insulating layer is S 3 , and an area of the second electrode is S 4 , S 1 ≦S 2 <S 3 and S 2 <S 4 are satisfied.
