Organic electroluminescent lighting system including wiring including a plurality of openings

摘要

It is an object of the present invention to provide a lighting system having favorable luminance uniformity in a light-emitting region when the lighting system has large area. According to one feature of the invention, a lighting system comprises a first electrode, a second electrode, a layer containing a light-emitting substance formed between the first electrode and the second electrode, an insulating layer which is formed over a substrate in a grid form and contains a fluorescence substance, and a wiring formed over the insulating layer. The insulating layer and the wiring are covered with the first electrode so that the first electrode and the wiring are in contact with each other.
