Patent ID: 8097892

Claim:
A light-emitting diode having a main light-extracting surface and comprising: a compound semiconductor layer including semiconductor layers; a light-emitting part contained in the compound semiconductor layer; a light-emitting layer contained in the light-emitting part; a transparent substrate joined to the compound semiconductor layer; and first and second electrodes of opposite polarities formed on the main light-extracting surface on a side opposite the transparent substrate; wherein the second electrode is formed at a position on a portion of the compound semiconductor layer exposed by removal of the light-emitting layer and has a periphery which is entirely enclosed with the light-emitting part whose light-emitting layer is not removed; and wherein the main light-extracting surface has an external shape having a largest width of 0.8 mm or more; wherein the transparent substrate contains a first side face nearly perpendicular and falling on a side of the light-emitting part and a second side face continuing to the first side face and having an inclined surface formed on a side distant from the light-emitting layer; and wherein the inclined surface of the second side face has an angle of inclination that is 10° or more and less than 20° and wherein the light-emitting part, when seen as projected on a light-emitting surface, has part thereof formed above the second side face.
