Abstract
A light-emitting diode includes a semiconductor light-emitting stack, a transparent conductive layer, a first current blocking layer, and a first electrode pad. The transparent conductive layer is disposed on the semiconductor light-emitting stack, and is formed with a first opening defined by an inner edge thereof. The first current blocking layer is formed on the semiconductor light-emitting stack, and is surrounded by and spaced apart from the inner edge of the transparent conductive layer by a first gap. The first electrode pad fully covers the first current blocking layer so as to permit the first electrode pad to be in contact with the semiconductor light-emitting stack through the first gap.
