Light emitting diode chip with double close-loop electrode design

An LED chip with double close-loop electrode design includes a substrate, a first-type doped semiconductor layer, a light emitting layer, a second-type doped semiconductor layer, a first electrode and a second electrode. The first-type doped semiconductor layer is disposed on the substrate, the light emitting layer is disposed on the first-type doped semiconductor layer and the second-type doped semiconductor layer is disposed on the light emitting layer. The first electrode, disposed on the first-type doped semiconductor layer, has a close-loop pattern. The second electrode, disposed on the second-type doped semiconductor layer, is located inside a region encircled by the first electrode and has a close-loop pattern. In this way, the LED chip with double close-loop electrode design is able to avoid deteriorated luminous efficiency caused by broken electrodes.
