Abstract:
1. A light diffusing film having, on at least one surface of a base film, a light diffusing layer made of an inorganic or organic light diffuser and a binder resin, wherein the base is a polymeric resin film without a filler, satisfying the following formulae: wherein T is the transmittance of the base film with respect to light having a wavelength of 400 to 900 nm, I is the intensity of light after passing through the base film, I o is the intensity of light before passing through the base film; wherein T is the transmittance of the base film with respect to light having a wavelength of 400 to 900 nm, and T d is the diffusing transmittance; wherein H t is the longitudinal heat shrinkage of the base film, being 1.0 or less, and H m is the transverse heat shrinkage of the base film, being 1.0 or less.
