Abstract
A light emitting diode (LED) chip including a first type semiconductor layer, an light-emitting layer, a second type semiconductor layer, a current blocking layer, a transparent conductive layer and an electrode is provided. The light-emitting layer is disposed on the first type semiconductor layer. The second type semiconductor layer is disposed on the light-emitting layer. The current blocking layer is disposed on the second type semiconductor layer. The transparent conductive layer is disposed on the second type semiconductor layer and covered the current blocking layer. The electrode is disposed on the transparent conductive layer corresponding to the current blocking layer. The current blocking layer and the electrode respectively have a first width and a second width in a cross section view, and the first width of the current blocking layer is larger than the second width of the electrode.
