<p>Disclosed is a scattering film which can be used in an organic EL light-emitting device, in which the light utilization efficiency and field-of-view dependence, which have been problems so far in organic EL light-emitting devices, can be improved without interfering the two properties with each other. Specifically disclosed is a scattering film for an organic EL, which can be placed on the light emission surface side of an organic EL light-emitting device for use, and involves a scattering layer, wherein the scattering layer comprises a binder resin, microparticles having a different refractive index from that of the binder resin, and resin particles having a larger average particle diameter than that of the microparticles. The content of the microparticles is preferably 5 to 90 parts by weight relative to 100 parts by weight of the binder resin, and the content of the resin particles is preferably 100 to 300 parts by weight relative to 100 parts by weight of the binder resin.</p> |
