Light-emitting element, light-emitting device, display device, electronic appliance, and lighting device

A light-emitting element comprising:

• a first electrode,
• a second electrode, and
• an electroluminescence layer interposed between the first electrode and the second electrode,
• wherein the electroluminescence layer comprises a light-emitting layer in which a first light-emitting layer and a second light-emitting layer are stacked,
• wherein the first light-emitting layer contains a first organic compound, a second organic compound, and a fluorescent substance,
• wherein the second light-emitting layer contains a third organic compound and a phosphorescent substance,
• wherein a combination of the first organic compound and the second organic compound forms a first exciplex,
• wherein the first light-emitting layer is a fluorescent layer,
• wherein the second light-emitting layer is a phosphorescent layer, and
• wherein the first organic compound and the second organic compound are mixed in the first light-emitting layer to form a single light-emitting layer.
