Patent ID: 8168996

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 openings in the insulating film which are separated from each other exposing regions which are external connecting parts of the second electrode spaced from each other, wherein in the same surface side: the first electrode comprises a plurality of first electrodes which are not connected to each other in said surface side on the first conductive type semiconductor layer, said plurality of first electrodes being arranged to form two separate one-dimensional first electrode arrays which are parallel to each other and spaced from each other, each first electrode array comprising a plurality of separated first electrodes, and a plurality of the external connecting parts of the second electrode are arranged to form a second electrode array substantially parallel to the first electrode arrays, and the second electrode array is provided in between the two first electrode arrays but not overlapping with the two first electrode arrays in the one-dimensional direction of the first electrode arrays.
