Abstract:
Provided are an optical diffusion film composed of a single layer, for which the optical diffusion incident angle region can be effectively expanded, and even when the incident angle of incident light is varied within the optical diffusion incident angle region, changes in the optical diffusion characteristics can be effectively suppressed; and a method for manufacturing the optical diffusion film. Disclosed is an optical diffusion film having, inside the film, a single optical diffusion layer having a first internal structure and a second internal structure, each of which include a plurality of regions having a relatively high refractive index in a region having a relatively low refractive index, sequentially from the lower part along the film thickness direction, and the regions having a relatively high refractive index in the first internal structure have a bent section at an intermediate point along the film thickness direction.

Claim (Index 13):
An optical diffusion film comprising, inside the film, a single optical diffusion layer having a first internal structure and a second internal structure, each of the internal structures including a plurality of regions having a relatively high refractive index in a region having a relatively low refractive index, sequentially from the lower part along the film thickness direction,\n wherein the first internal structure is a louver structure in which a plurality of plate-shaped regions having different refractive indices are alternately disposed in any one direction along the film plane, wherein the second internal structure is a columnar structure in which a plurality of pillar-shaped objects having a relatively high refractive index are arranged to stand close together in the film thickness direction in a region having a relatively low refractive index, wherein the regions having a relatively high refractive index in the first internal structure have a bent section at an intermediate point along the film thickness direction, wherein in the first internal structure, the angle of inclination \u03b8a, with respect to the normal line of the film plane, of the regions having a relatively high refractive index in the portion upper than the bent section is adjusted to a value within the range of 0\u00b0 to 30\u00b0, and the angle of inclination \u03b8b, with respect to the normal line of the film plane, of the regions having a relatively high refractive index in the portion lower than the bent section is adjusted to a value within the range of 1\u00b0 to 60\u00b0, and wherein the absolute value of \u03b8b\u2212\u03b8a is adjusted to a value within the range of 1\u00b0 to 30\u00b0 or less.
