Light-emitting diode

A light-emitting diode comprising:

• a semiconductor light-emitting stack which includes, in sequence from bottom to top, a second conductivity type semiconductor layer, alight-emitting layer, and a first conductivity type semiconductor layer;
• a transparent conductive layer disposed on said first conductivity type semiconductor layer, and formed with a first opening which is defined by an inner edge of said transparent conductive layer;
• a first current blocking layer formed on said first conductivity type semiconductor layer, and surrounded by and spaced apart from said inner edge of said transparent conductive layer by a first gap which has a predetermined width;
• and
• a first electrode pad formed on said first current blocking layer to fully cover an upper surface and an outer peripheral surface of said first current blocking layer so as to permit said first electrode pad to be in contact with said first conductivity type semiconductor layer through said first gap.
