Abstract:
1. A light emitting device comprising: a light emitting structure comprising a first conductive type semiconductor layer, a second conductive type semiconductor layer under the first conductive type semiconductor layer, and an active layer between the first conductive type semiconductor layer and the second conductive type semiconductor layer; and an electrode connected to the first conductive type semiconductor layer; a first conductive support member disposed under the light emitting structure; a conductive contact layer disposed between the second conductive type semiconductor layer and the first conductive support member; plurality of metal layers disposed between the conductive contact layer and the first conductive support member; and a second conductive support member disposed under the first conductive support member, wherein the second conductive support member comprises a different material from the first conductive support member, wherein the second conductive support member has a thermal conductivity higher than that of the first conductive support member, wherein the second conductive support member has a thickness smaller than a thickness of the first conductive support member, and wherein the second conductive support member is located at a lower position than a position of the first conductive support member.
