Abstract:
Disclosed is a light-diffusing film (1) wherein a laminated body (5) having a multilayer structure is formed by laminating materials that constitute a structural body (4). The structural body (4) is formed by melting the laminated body (5) or by covering the laminated body (5) with a resin. Alternatively, the structural body (4) may be formed by laminating a plurality of tapered layers. In this case, the layer width of the structural body (4) is reduced toward the upper layer from the lower layer, and as a whole, the structural body has a structure having tilted surfaces that are tilted at multiple levels. The shape of the structural body (4) can be controlled by micron size by adjusting the number of layers, height, width and the like of the structural body (4) as needed.
