Abstract
The present invention provides a light-emitting diode that includes two electrodes provided on a light-emitting surface, and exhibits high light extraction efficiency and high-brightness. The present invention relates to a light-emitting diode () including: a compound semiconductor layer () including a light-emitting portion () containing a light-emitting layer (); and a transparent substrate (), wherein the compound semiconductor layer () and the transparent substrate () are bonded, and a first electrode () and a second electrode () are provided on the side of a main light-emitting surface () of the compound semiconductor layer (), wherein the transparent substrate () includes: an upper surface (A) bonding to the compound semiconductor layer (); a bottom surface (B) having smaller dimensions than dimensions of the upper surface (A); 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 () and () are disposed within a region in which the bottom surface (B) is projected when viewed from the top of the light-emitting diode.
