Abstract: A light emitting device (LED) includes a stress control layer having a compressive stress on a substrate, a bonding layer on the stress control layer, a semiconductor layer on the bonding layer and including an active region for emitting light on the bonding layer, a first electrode on a lower surface of the substrate, and a second electrode on the semiconductor layer. The compressive stress of the stress control layer is between about 1 and about 20 GPa.
