The present invention relates to a light diffusion film which effectively extends the diffusion surface of light by diffusing the light in a horizontal direction and an orthogonal direction. For this, the light diffusion film includes a first louver structure and a second louver structure in order according to the thickness direction of a film. The first louver structure and the second louver structure include a plurality of surface areas according to each refractive index. The louver structures are alternately arranged in parallel, and the acute angle between the extension direction of the surface area in the first louver structure and the extension direction of the surface area in the second louver structure is within an angle of 10-90 degrees. |
