US Patent 7679284 Light emitting device and electronic apparatus

A light emitting device includes a substrate, a plurality of light emitting elements, an element layer, an auxiliary electrode, and an insulating layer. An effective region in which the plurality of light emitting elements are arranged and a peripheral region that surrounds the effective region are provided on the substrate. Each of the light emitting elements includes a first electrode, a second electrode and a light emitting layer located between the first electrode and the second electrode. A circuit element is arranged in the element layer to control emission of light of the light emitting elements. The auxiliary electrode is electrically connected to the second electrode. The second electrode covers the effective region and is formed uniformly so as to extend into the peripheral region. The auxiliary electrode extends through a gap between adjacent light emitting elements in the effective region and is formed partly in the peripheral region.
