Abstract
A light-emitting diode device includes an epitaxial layer, a current blocking layer and a current spreading layer. The current blocking layer is disposed on one side of the epitaxial layer and contacts with a portion of the epitaxial layer. The current spreading layer is disposed on one side of the epitaxial layer and contacts with at least a portion of the current blocking layer.
