Abstract
A light-emitting diode includes an N-type cladding layer, and a superlattice structure, an active layer, a P-type electron-blocking layer, and a P-type cladding layer disposed on the N-type cladding layer in such order. The superlattice structure includes at least one first layered element which has a sub-layer made of a nitride-based semiconductor material including Al, and having an energy band gap greater than that of said electron-blocking layer. The P-type electron-blocking layer is made of a nitride-based semiconductor material including Al, and has an energy band gap greater than that of the P-type cladding layer.
