Abstract: A light extraction film for EL elements enables a surface light emitting body to have a good balance between suppression of emission angle dependence of the wavelength of emitted light and improvement of light extraction efficiency and luminance in the normal direction. A surface light emitting body has improved light extraction efficiency and luminance in the normal direction, while being suppressed in emission angle dependence of the wavelength of emitted light. A light extraction film for EL elements comprises a recessed and projected structure having a plurality of spherical projections, each containing a resin and fine particles added into the resin. The content of the fine particles in the spherical projections is 22-55% by mass, and the average maximum diameter (Aave) of the bottom portions of the spherical projections and the volume average particle diameter (P) of the fine particles satisfy the following mathematical formula (1).

Abstract: A laminate is described, including a substrate, an undercoat layer on the substrate, and an inorganic film on the undercoat layer. The material of the inorganic film is at least one material of a conductive metal oxide and a metal nitride. In an image obtained by Fourier transforming an image obtained by using an atomic force microscope to take a picture of a surface of the inorganic film, the azimuth angle of the image obtained from the Fourier transformation from the center of the image toward the direction of 12 o'clock is set to 0°. In approximate curves of 36 brightness value plots obtained by radially plotting the brightness values every 10° from 0°, a maximum value is observed in 18 or more of the approximate curves.
