Abstract
This light-extraction film for EL includes a diffusion layer and an uneven-structure layer, the diffusion layer including first light-diffusion fine particles, and the uneven-structure layer including second light-diffusion fine particles as desired, and satisfying the expression Px−Py≧5 mass %. (Px represents the content ratio of the first light-diffusion fine particles to the total mass of the diffusion layer. Py represents the content ratio of the second light-diffusion fine particles to the total mass of the uneven structure layer.)
