In addition, a light-emitting element with high color purity and high emission efficiency is provided. Furthermore, a light-emitting device having a long lifetime in which the light-emitting element is used is provided. Moreover, an electronic device and a lighting device each of which has a long lifetime are provided. In the light-emitting element including an EL layer between a pair of electrodes, the EL layer has a stacked-layer structure of a first light-emitting layer, a second light-emitting layer, and a third light-emitting layer. The light-emitting layer includes an electron-transport material, a hole-transport material, and a light-emitting material. Furthermore, light emitted from the first light-emitting layer and light emitted from the third light-emitting layer have the same color and each have a longer wavelength than light emitted from the second light-emitting layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light-emitting element, light-emitting device, electronic device, and lighting device","description":"A highly reliable light-emitting element which can keep favorable characteristics throughout long-time driving is provided.
