Abstract:
1. A light-emitting diode comprising a compound semiconductor layer including a p-n junction-type light-emitting part, an electric conductor disposed on the compound semiconductor layer and formed of an electrically conductive material optically transparent to light emitted from the light-emitting part, a high resistance layer possessing higher resistance than the electric conductor and provided in a middle between the compound semiconductor layer and the electric conductor, and a second compound semiconductor layer of a type of conductivity opposite to the electric conductor, which layer is bonded to a surface of the high resistant layer opposite to a side thereof bonded to the electric conductor; wherein a breakdown voltage of a bond formed of the electric conductor, the high resistance layer and the second compound semiconductor layer during a flow of an electric current of 10 μA exceeds 2 times a forward voltage of the light emitting diode during a flow of an electric current of 10 μA and smaller than ½ of a reverse voltage of the light-emitting diode during a flow of an electric current of 10 μA.
