Abstract:
1. A compound semiconductor light-emitting diode comprising: a light-emitting layer formed of aluminum-gallium-indium phosphide ((Al component layers individually having a light-emitting part formed of a Group III-V compound semiconductor; a transparent supporting layer bonded to an outermost surface layer of the light-emitting part and transparent to light emitted from the light-emitting layer; and a bonding layer formed between the supporting layer and the outermost surface layer of the light-emitting part and containing oxygen atoms at a concentration of 1 ×10 wherein the outermost surface layer of the light-emitting part whose side is bonded to the supporting layer and the supporting layer are both formed of gallium phosphide (GaP), and wherein the bonding layer has a nonstoichiometric composition represented by formula Ga
