Patent ID: 8362516

Claim:
A semiconductor light emitting device comprising: a first electrode and a second electrode respectively provided on a first conductive type semiconductor layer and a second conductive type semiconductor layer on a same surface side, the first conductive type semiconductor layer having a different conductive type from the second conductive type semiconductor layer, and an insulating film disposed on the second electrode, and at least one opening in the insulating film exposing at least one region, said at least one region forming at least one external connecting part of the second electrode, wherein in the same surface side: the first electrode comprises a plurality of first electrodes arranged to form a one-dimensional first electrode array, wherein said first electrodes are not connected to each other in said surface side on the first conductive type semiconductor layer, and each of said first electrodes in said plurality of first electrodes comprises a base part, and two extended parts extending from the base part, such that said plurality of first electrodes comprise a plurality of said base parts, wherein said plurality of base parts are aligned in the one-dimensional direction of the first electrode array, a first plurality of extended parts includes one of said two extended parts from each of said first electrodes, a second plurality of extended parts includes the other of said two extended parts from each of said first electrodes, said first plurality of extended parts are aligned in the one-dimensional direction of the first electrode array, on a first side of said plurality of base parts, and said second plurality of extended parts are aligned in the one-dimensional direction of the first electrode array, on a second side opposite to said first side of said plurality of base parts, and a portion of said at least one external connecting part of the second electrode is arranged in between two extended parts of different first electrodes in the first electrode array, such that said portion of said at least one external connecting part overlaps with the two extended parts of said different first electrodes, in the one-dimensional direction of the first electrode array.
