摘要：PROBLEM TO BE SOLVED: To provide a light emitting device which reduces membrane resistance of an electrode forming a light emitting element.SOLUTION: A light emitting device comprises: light emitting regions, each of which is formed by a first electrode 11, a second electrode 20, an organic compound layer 17 sandwiched by the first electrode 11 and the second electrode 20; an insulation object 24 located on the first electrode 11; the second electrode 20 located on the insulation object; and an auxiliary electrode 21 contacting with a lower surface of the second electrode 20 in a region that excludes the light emitting regions. The structure of the light emitting device enables low resistance and a thin film of the second electrode 20. Further, the second electrode is electrically connected with an electrode of a terminal part connected with a flexible printed circuit and may be extracted.
