Light diffusion film with uniform surface roughness and low retardation value and method for manufacturing the same

摘要

A light diffusion film includes a thermoplastic resin, a surface of the light diffusion film has a roughness (Ra) of about 0.5 to about 3μm and a height distribution index (HDI) of about 3 to about 8μm, and the light diffusion film has a retardation of not more than about 25 nm.
