Patent ID: 8847479

Claim:
A lighting system comprising: an insulating layer formed over a substrate in a grid form, wherein the insulating layer includes a plurality of openings, and the plurality of openings each pass completely through the insulating layer; a wiring over and in contact with the insulating layer, wherein the wiring includes a plurality of openings corresponding to the plurality of openings of the insulating layer, and the plurality of openings of the wiring each pass completely through the wiring; a first electrode over and in contact with the wiring and the insulating layer; a layer including a light-emitting substance over the first electrode and the wiring; and a second electrode over the layer including the light-emitting substance, wherein each opening of the plurality of openings of the insulating layer overlaps with the first electrode, wherein each opening of the plurality of openings of the wiring overlaps with the first electrode, wherein each opening of the plurality of openings of the insulating layer overlaps with the second electrode, wherein each opening of the plurality of openings of the wiring overlaps with the second electrode, wherein the first electrode continuously extends so as to overlap with the plurality of openings of the insulating layer and the plurality of openings of the wiring, and wherein the second electrode continuously extends so as to overlap with the plurality of openings of the insulating layer and the plurality of openings of the wiring.
