Abstract:
There is provided a scattering film that can be used in organic EL light emitting devices and that not only improves efficiency for light utilization and improves viewing angle dependency, which have conventionally been problems, but also can solve the problem of reflection when lights-off. This scattering film for organic EL is used in organic EL light emitting devices. The scattering film comprises a scattering layer that includes a binder resin and particles having a refractive index different from the binder resin. The average particle size of the particles is 10 μm or less, and the coefficient of variation of the average particle size for the particles is 30% or greater.
