Abstract:
An embodiment of the present invention relates to a light emitting device capable of enhancing ohmic characteristics of a semiconductor layer and an electrode and simultaneously improving driving voltage, comprising: a support substrate; a light emitting structure which is disposed on the support substrate and comprises a first semiconductor layer, a second semiconductor layer and an active layer disposed between the first semiconductor layer and the second semiconductor layer; at least one groove which exposes the first semiconductor layer through the second semiconductor layer and the active layer; a first electrode which is disposed between the light emitting structure and the support substrate and electrically connected to the exposed first semiconductor layer; a second electrode which comprises ITO and contacts the second semiconductor layer; and a capping layer which is electrically connected, between the first electrode and the light emitting structure, to the second electrode, wherein the capping layer comprises a first layer, which is disposed facing the second semiconductor layer, with the second electrode interposed therebetween and comprises a material having a thermal expansion coefficient different from the thermal expansion coefficient of the second semiconductor layer by 3 or less.

Claim (Index 1):
A light emitting device comprising:\n a support substrate; a light emitting structure disposed on the support substrate and including a first semiconductor layer, a second semiconductor layer, and an active layer interposed between the first semiconductor layer and the second semiconductor layer; at least one groove which passes through the second semiconductor layer and the active layer and exposes the first semiconductor layer; a first electrode interposed between the light emitting structure and the support substrate and electrically connected to the exposed first semiconductor layer; a second electrode in contact with and electrically connected to the second semiconductor layer; and a capping layer interposed between the support substrate and the light emitting structure and electrically connected to the second electrode, wherein the capping layer is disposed to face the second semiconductor layer with the second electrode interposed therebetween and includes a first layer having a material of which a difference in thermal expansion coefficient with the second semiconductor layer is 3 or less.
