ABSTRACT:
An anisotropic scattering film, wherein said film has a sea-island structure comprising a matrix phase consisting of at least one polymeric material, and a dispersed phase consisting of at least one polymeric material, wherein the dispersed phase is rod-like, the dispersed phase substantially orientates to one direction, the refractive index of the dispersed phase in the major axis direction differs from the refractive index of the matrix phase in the corresponding direction, the diameter of the dispersed phase is 200 nm or less, and the length of the dispersed phase is 800 nm or more.
