ABSTRACT:
In a prior-art injection type light emitting device which is constructed so that a predetermined range of a p-n junction formed by a semiconductor substrate and an epitaxial layer provided thereon may radiate, a radiation region in the p-n junction becomes larger in area than the region into which current is introduced, on account of the current spreading phenomenon. The construction of a light emitting device free from the phenomenon and a method for manufacturing the light emitting device are disclosed.
