发明名称 LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, DISPLAY DEVICE, ELECTRONIC DEVICE, AND LIGHTING DEVICE
摘要 A light-emitting element having high emission efficiency is provided. A light-emitting element which has high emission efficiency without using a rare metal as a light-emitting material is provided. A light-emitting element includes a first electrode, a second electrode, and a layer between the first electrode and the second electrode. The layer contains a first organic compound and a second organic compound. The second organic compound has a carbazole skeleton and a substituted or unsubstituted bivalent aromatic hydrocarbon group. The second organic compound further has a benzofuropyrimidine skeleton or a benzothienopyrimidine skeleton. The aromatic hydrocarbon group is bonded to the carbazole skeleton. The aromatic hydrocarbon group is bonded to the benzofuropyrimidine skeleton or the benzothienopyrimidine skeleton. The first organic compound and the second organic compound can form an exciplex.
