Abstract
A light-emitting diode (LED) includes a substrate, an epitaxial structure, and an electrode structure. The epitaxial structure includes a first semiconductor layer, an active layer and a second semiconductor layer that are sequentially disposed on the substrate in such order. The electrode structure includes electrodes that are respectively disposed on the first and second semiconductor layers opposite to the substrate. Each electrode has an upper surface that is opposite to the first and second semiconductor layers. The electrode structure also includes an insulating unit that is disposed in each electrode, and that is not exposed from the upper surface of the corresponding electrode.
