Abstract: A light-emitting diode chip is described. The light-emitting diode chip includes a light-emitting structure, a first electrode, and a second electrode. The first electrode is disposed on the light-emitting structure and is electrically connected to the light-emitting structure. The second electrode is disposed on the light-emitting structure, and the second electrode and the first electrode are located on the same side of the light-emitting structure, wherein the second electrode is electrically connected to the light-emitting structure. The light-emitting diode chip has a first surface and a second surface which are opposite to each other, and a side surface connected between the first surface and the second surface. The side surface is substantially perpendicular to the first surface and the second surface, and an included angle between the side surface and the first surface is between 86 degrees and 94 degrees.
