Abstract:
1. A semiconductor light emitting device comprising: a stacked structural body including: a first electrode provided on the second portion of the first semiconductor layer; and a second electrode provided on the second semiconductor layer, the first electrode including: the first extending portion including a first width-increasing portion, a width of the first width-increasing portion along a direction orthogonal to the first extending direction being increased from the first pad portion toward an end of the first extending portion; wherein the second electrode includes: a third extending portion extending from the second pad portion, at least a part of the third extending portion extending along a third extending direction different from the second extending direction; wherein the first conductivity type is n-type, the second conductivity type is p-type, the second extending portion and the third extending portion extend from a position of the second pad portion which is receded from a position which is closest to the first extending portion, the width of the first width-increasing portion along a direction orthogonal to the first extending direction gradually increases from a start position toward an end position, the start position being on a side of the first pad from a center position along the first extending direction in the first extending portion, and the end position being an end of the first extending portion.
