Abstract
A light-emitting diode (10) includes a transparent substrate and a compound semiconductor layer that contains a light-emitting part (12) containing a light-emitting layer (133) formed of (AlxGa1-x)YIn1-YP; in which 0 ≤X≤1 and 0 < Y≤1), and that is joined to the transparent substrate (14). wherein the light-emitting diode (10) has on a main light-extracting surface thereof a first electrode (15) and a second electrode (16) different in polarity from the first electrode, the transparent substrate has side faces that are a first side face (142) roughly perpendicular to a light-emitting surface of the light-emitting layer on a side near the light-emitting layer and a second side face (143) inclined relative to the light-emitting surface on a side distant from the light-emitting layer and coarsened with irregularities falling in a range of 0.05 μm to 3 μm. The light-emitting diode provided on the light-extracting surface with the two electrodes manifests a high efficiency of light extraction and high brightness.
