摘要： A light-emitting device, an electronic device, and a display device each consume less power are provided. The light-emitting device includes a first light-emitting element, a second light-emitting element, and a third light-emitting element that share an EL layer. The EL layer includes a layer containing a light-emitting material that emits blue fluorescence and a layer containing a light-emitting material that emits yellow or green phosphorescence. Light emitted from the second light-emitting element enters a color filter layer or a second color conversion layer, and light emitted from the third light-emitting element enters a first color conversion layer.

摘要： The present invention provides a metal platinum complex, an organic optoelectronic device, and a display or lighting apparatus. A new 6/5/7 metal fused-ring structure is developed by using 8-phenylquinoline structure and a derivative thereof, and benzo five-membered heterocycles and a phenoxy oxygen tetradentate ligand, to obtain a new class of tetradentate cyclometalated platinum complex phosphor material. A chemical formula of the phosphor material is shown as the general formula (1):
