A high-efficiency light diffusing polymeric film comprises a first polymer which is a light transmissible medium, and a second polymer which forms light scattering particles, wherein the polymers are immiscible and have a refractive index difference of about 0.001 to about 0.5, and the polymeric film comprises about 30 about to 70 parts by weight of the second polymer with respect to 100 parts by weight of the first polymer. A method for manufacturing a high-efficiency polymeric film is carried out such that a first polymer forms a continuous phase and a second polymer forms a dispersed phase through coating or extrusion.
