The present invention relates to a light diffusing film, a method for manufacturing same, and a backlight unit using same for a liquid crystal display. The light diffusing film according to the present invention has a structure comprising fiber layers unidirectionally arrayed in parallel, of which two or more layers are multi-axially arrayed in alternation from a combination of two or more angles from among the angles 0°, 90° or ±&thetas;, causing the incident light to scatter two-dimensionally, and thus even diffusion of light is attained regardless of the initial direction of incident light, and by simultaneously extruding transparent polymer resin which a matrix ingredient, and birefringent organic fibers of the fiber layer, and arraying nano-fibers, comprising birefringent organic fibers, in situ within the matrix, the present invention has the benefit of simultaneously shortening the process and thinning the thickness. Furthermore, by using the light diffusing film according to the present invention, a liquid crystal display backlight unit having high opacity and improved light diffusion property can be provided. |
