Patent ID: 8729598

Claim:
A light-emitting diode comprising: a compound semiconductor layer including a light-emitting portion containing a light- emitting layer consisting of a composition formula (Al X Ga 1-X ) Y In 1-Y P(0≦X≦1,0<Y≦1), Al X Ga 1-X As(0≦X≦1), or In X Ga 1-X As(0≦X≦0.3); and a transparent substrate, wherein the compound semiconductor layer and the transparent substrate are bonded, and a first electrode and a second electrode having a polarity different from that of the first electrode are provided on the side of a main light-emitting surface of the compound semiconductor layer, wherein the transparent substrate comprises: an upper surface bonding to the compound semiconductor layer; a bottom surface having smaller dimensions than dimensions of the upper surface; and a side surface including at least inclined surface inclined from the side of the upper surface toward the side of the bottom surface, wherein the first and second electrodes are disposed within a region in which the bottom surface is projected when viewed from the top of the light-emitting diode, and not disposed within a region in which the inclined surface of the transparent substrate is projected when viewed from the top of the light-emitting diode.
