A protective layer and a planarization layer are disposed in this order on the light emission side of whichever of the first and second electrodes is closer to the light emission side. A surface of the protective layer adjacent to the planarization layer has an uneven shape. The planarization layer is in contact with the protective layer. A surface of the planarization layer away from the protective layer is flat. The refractive index of the planarization layer is equal to or lower than that of the protective layer and equal to or higher than that of a light emission medium in contact with the planarization layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Organic electroluminescent element and light-emitting device","description":"An organic electroluminescent element includes a first electrode, a second electrode, and an organic compound layer disposed between the first and second electrodes.
