摘要：A light extraction film of the present invention relates to a light extraction filmfor EL elements, which enables a surface light emitting body to have a sufficientlyimproved luminance in the normal direction, while being sufficiently suppressed in
emission angle dependence of the wavelength of light emitted therefrom. More
specifically, the present invention relates to a light extraction film () which is laminated ona substrate of an EL element, and which has a recessed and projected structure () on thesurface. The materials that constitute this light extraction film () contain a resin (X) thathas at least one skelton selected from among a fluorene skeleton, a biphenyl skeletonand a naphthalene skelton.
