A light emitting diode chip includes a substrate, an epitaxial layer, two inclined plane units, and two electrode units. The substrate has top and bottom surfaces. The epitaxial layer is disposed on the top surface of the substrate. Each of the inclined plane units is inclined downwardly and outwardly from the epitaxial layer toward the bottom surface of the substrate, and includes an inclined sidewall formed on the epitaxial layer, and a substrate inclined wall formed on the substrate. Each of the electrode units includes an electrode disposed on the epitaxial layer, and a conductive portion extending from the electrode to the substrate inclined wall along corresponding one of the inclined plane units.
