摘要：
An organic EL light-emitting device including: a light-emitting layer capable of generating light; a light-scattering structure capable of scattering the light; a first light-scattering layer containing first light-scattering particles having an average particle diameter of 0.1 μm to 2 μm and a first binder; and a concavo-convex structure in a streak array pattern, the light emitting layer, the light-scattering structure, the first light-scattering layer, and the concavo-convex structure being disposed in this order, wherein a mean free path L1 of light scattering in the first light-scattering layer and a thickness D1 of the first light-scattering layer satisfy D1/L1
