Patent ID: 8299477

Claim:
A light emitting device, comprising: a metallic layer; a plurality of light emitting device cells arranged above the metallic layer, and including a first conductive semiconductor layer, an active layer below the first conductive semiconductor layer, and a second conductive semiconductor layer below the active layer; a connection section connecting the light emitting device cells to each other in series; an insulating layer provided between the metallic layer and the light emitting device cells, and including a first insulating layer electrically insulating the light emitting device cells from each other and a second insulating layer insulating the connection section from the metallic layer; electrodes provided above the first conductive semiconductor layer of the light emitting device cells; a contact section connecting the second conductive semiconductor layer of the light emitting device cells to the metallic layer through a contact hole formed in the second insulting layer, and forming a first node; and a pad provided on at least one of the electrodes, and forming a second node, wherein each light emitting device cell is directly physically connected with the connection section through a hole formed in the first insulating layer, and wherein the electrodes are not in direct physical contact with the connection section.
