Patent ID: 7839083

Claim:
A light emitting device comprising: a substrate on which an effective region and a peripheral region that surrounds the effective region are provided; a plurality of light emitting elements that are arranged in the effective region, wherein each of the plurality of light emitting elements includes a first electrode, a second electrode and a light emitting layer located between the first electrode and the second electrode, wherein the second electrode is commonly provided for the plurality of light emitting elements; an element layer in which a circuit element is arranged to control emission of light of the light emitting elements; an auxiliary electrode that is electrically connected to the second electrode; and an insulating layer that has a portion that is arranged in an upper layer on the element layer and arranged in a lower layer under the second electrode and the auxiliary electrode, wherein the insulating layer insulates the second electrode and the auxiliary electrode from the circuit element, wherein the second electrode covers the effective region and is formed uniformly so as to extend into the peripheral region, wherein in the effective region, the auxiliary electrode extends through a gap formed between the plurality of adjacent light emitting elements and is formed partly in the peripheral region, and wherein in the peripheral region, an end portion of the second electrode is located on an inner side along a plane of the substrate than an end portion of the auxiliary electrode and located on an outer side than an end portion of the insulating layer.
