Claim:
1. A light emitting device comprising: a support substrate; a reflective layer on the support substrate; a first layer including ohmic contact regions and a plurality of insulating regions on the reflective layer; a light emitting semiconductor layer disposed on the first layer and including a second conductive semiconductor layer, an active layer on the second conductive semiconductor layer, and a first conductive semiconductor layer on the active layer; an electrode on a top surface of the first conductive semiconductor layer; a light extracting structure on the top surface of the first conductive semiconductor layer, a roughness disposed over the plurality of the insulating regions; and a passivation layer disposed on top and side surfaces of the light emitting semiconductor layer, the passivation layer being in contact with the first layer, wherein the light extracting structure is disposed adjacent to the electrode, and wherein the insulating regions extend radially from a center of the ohmic contact regions.
