Original Abstract Submitted
a light-emitting device with favorable characteristics is provided. in a plurality of light-emitting devices each including an organic compound layer formed over the same insulating surface, the organic compound layer includes a first light-emitting layer, a second light-emitting layer, and an intermediate layer. the intermediate layer includes a first layer. the first layer includes a metal or metal compound, a first organic compound, and a second organic compound. the first organic compound includes a �-electron deficient heteroaromatic ring. the second organic compound includes two or more heteroaromatic rings that are bonded or condensed to each other and include three or more heteroatoms in total. the second organic compound interacts with the metal or metal compound by two or more of the three or more heteroatoms as a multidentate ligand.
