Abstract:
1. A semiconductor light emitting device comprising: a stacked structural body including a first semiconductor layer of a first conductivity type including a nitride semiconductor, a second semiconductor layer of a second conductivity type including a nitride semiconductor, and a light emitting layer including a nitride semiconductor provided between the first semiconductor layer and the second semiconductor layer; a first conductive layer, the second semiconductor layer being disposed between the first conductive layer and the light emitting layer, the first conductive layer being transparent with respect to luminescent light emitted from the light emitting layer, the first conductive layer having a first major surface on a side opposite to the second semiconductor layer; a second conductive layer in contact with the first major surface and covering a portion of the first major surface; and a third conductive layer in contact with the first major surface and having a reflectance higher than a reflectance of the second conductive layer with respect to the luminescent light, the third conductive layer including an extending part extending in parallel to the first major surface, at least a portion of the extending part being not covered by the second conductive layer, wherein the second conductive layer covers an upper portion of the third conductive layer.
