Abstract

A light emitting diode chip including a substrate and a light emitting diode element layer is provided. The substrate has a growth surface and a plurality of microstructures on the growth surface. An area of the growth surface occupied by the microstructures is A1 and an area of the growth surface not occupied by the microstructures is A2, such that A1 and A2 satisfy the relation of 0.1≦A2/(A1+A2)≦0.5. The light emitting diode element layer is disposed on the growth surface of the substrate.
