    Abstract: PURPOSE: A resin composition for the optical scattering layer is provided to be used for the light extraction efficiency improvement of the organic EL device as the optical scattering layer set up between the light transmissive electrode and light-transmissive substrate. And the dependency for wave length of the light extraction efficiency improvement modulus is small and it can use in the wide wavelength area. CONSTITUTION: A resin composition for the optical scattering layer. It is the used resin composition for the optical scattering layer in order to form the optical scattering layer of the organic electro-luminescent device. It comprises the binder composition and the light scattering particle (B) including the resin (A) of at least one kind. The content of the particle which is the particle diameter 600nm or greater about the light scattering particle (B) whole quantity the average particle diameter among the resin composition for the optical scattering layer the light scattering particle (B) is over 200nm 500nm or less is 20 volume % or less. The refractive index difference of the light scattering particle (B) and binder composition is 0.1 or greater. The optical scattering layer is formed as the resin composition for the optical scattering layer is used. Second electrode (15) having the light reflectivity including the light-emitting layer and at least one organic layer (14) and first electrode (13) having the organic electro-luminescent device is the light-transmissive and optical scattering layer (12) on the light-transmissive substrate (11) are sequentially laminated.
