Abstract:
A light-emitting array having opposed long sides and opposed short sides and a plurality of semiconductor diffusion regions formed in a semiconductor layer by diffusing an impurity, comprising:an element-separating region, defining semiconductor blocks chat are electrically isolated front one another, each of the semiconductor blocks including a predetermined number of the plurality or semiconductor diffusion regions; and a common electrode formed in each of the semiconductor blocks and connected to the semiconductor layer; wherein said element-separating region includes a first separating region and a second separating region, the first separating region being formed to extend so that the semiconductor diffusion regions are between said element-separating region and the long side of the light-emitting array, the first separating region extending from one of the short sides to other one of the short sides, and the second separating region being formed to extend between adjacent semiconductor blocks, the second separating region having one end reaching the first separating region and the other end reaching one of the long sides.
