Patent ID: 6985295

Claim:
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: T = I I o × 100 ≥ 88 ⁢ % , 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; Haze ⁢ ⁢ ( % ) = T d T × 100 ≤ 1.2 , 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; 50 ⁢ % ≤ H t H m × 100 ≤ 100 ⁢ % , 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.
