Patent ID: 7126163

Claim:
A light-emitting diode comprising a light-emitting diode chip mounted on a surface of a printed substrate, the light-emitting diode chip including: a transparent substrate; a semiconductor layer laminated on the transparent substrate and formed of an N-type semiconductor layer and a P-type semiconductor layer, wherein a PN junction interface between the N-type and P-type semiconductor layers is perpendicular to the surface of the printed substrate, the semiconductor layer including: a light-emitting portion in the vicinity of the PN junction interface; and a first face and a second face, both the first face and the second face parallel to the transparent substrate wherein the first face is in contact with the transparent substrate; a first corner and a second corner adjacent to the surface of the printed substrate; a pair of electrodes for applying voltage to the semiconductor layer; a light reflecting layer formed of a metal thin film formed on the second face of the semiconductor layer substantially parallel to the PN junction interface and for reflecting light emitted from the light-emitting portion; and a recessed section formed only at the first corner of the semiconductor layer adjacent to the printed substrate, the recessed section formed by removing a portion of the light reflecting layer and a portion of the semiconductor layer to form an exposed surface of one of the N-type semiconductor layer and the P-type semiconductor layer; wherein a first electrode of the pair of electrodes is formed only at the second corner on the light reflecting layer and a second electrode of the pair of electrodes is formed on the exposed surface adjacent to the printed substrate.
