  • Patent number: 8158987
    Abstract: A transparent-substrate light-emitting diode (10) has a light-emitting layer (133) made of a compound semiconductor, wherein the area (A) of a light-extracting surface having formed thereon a first electrode (15) and a second electrode (16) differing in polarity from the first electrode (15), the area (B) of a light-emitting layer (133) formed as approximating to the light-extracting surface and the area (C) of the back surface of a light-emitting diode falling on the side opposite the side for forming the first electrode (15) and the second electrode (16) are so related as to satisfy the relation of A>C>B. The light-emitting diode (10) of this invention, owing to the relation of the area of the light-emitting layer (133) and the area of the back surface (23) of the transparent substrate and the optimization of the shape of a side face of the transparent substrate (14), exhibits high brightness and high exoergic property never attained heretofore and fits use with an electric current of high degree.
