Abstract:
1. A light emitting diode chip, comprising: a supporting substrate; a light emitting diode supported on the supporting substrate, wherein the light emitting diode has a bottom surface facing towards the supporting substrate, a top surface facing away from the supporting substrate, and a side surface extending between the bottom surface and the top surface, an area of the top surface is different from an area of the bottom surface, wherein the side surface of the light emitting diode includes a step profile along the side surface of the light emitting diode, wherein the light emitting diode further comprises: a protection layer covering a portion of the side surface between the bottom surface and the top surface, wherein said portion is closer to the supporting substrate than the top surface and does not extend to the top surface, and wherein the protection layer does not extend to between the bottom surface and the supporting substrate; and an electrode disposed on the top surface of the light emitting diode.
