ABSTRACT:
A light-emitting diode of a surface emitting type having a light-emitting part of a double heterostructure is constructed such that a drive current is concetrated in the light-emitting part beneath a light-emitting window, by forming a current block region beneath a contact provided adjacent the light-emitting window.
