Patent ID: 8101963

Claim:
A set of semiconductor light emitting elements arranged in a matrix, each of the light emitting elements comprising: an n-type semiconductor layer and a p-type semiconductor layer; an active layer disposed between the n-type semiconductor layer and the p-type semiconductor layer; an n-side electrode contacting the n-type semiconductor layer; a p-side electrode contacting the p-type semiconductor layer; and an insulating layer covering the n-type semiconductor layer and the p-type semiconductor layer in a manner such that part of the n-side electrode and part of the p side electrode is exposed; wherein the n-side electrode comprises a first layer made of Al and contacting the n-type semiconductor layer, and a second layer formed on the first layer and made of any one of Ni, W, Zr and Pt; wherein the p-side electrode comprises a first layer made of Au and contacting the p-type semiconductor layer, and a second layer formed on the first layer and made of any one of Ni, W, Zr and Pt; wherein a wiring formed directly on the insulating layer connects the n-side electrode of each light emitting element to the p-side electrode of an adjacent light emitting element; and wherein the wiring includes a first layer and a second layer formed on the first layer, the first layer of the wiring contacting the second layer of the n-side electrode and the second layer of the p-side electrode, the first layer of the wiring being made of a same material as that of the second layers of the n-side electrode and that of the p-side electrode.
