<p>Conventional production processes for light-diffusing films necessitate weaving the warp and weft together and therefore consume much time for making woven fabrics, thus resulting in low productivity. The invention relates to a process for the production of a light-diffusing film (10) comprising plural short fibers (11) and a transparent resin (12) for binding the short fibers (11) to each another. The process of the invention comprises the step (A) of converting plural short fibers (11) into a prefilm by papermaking method and the step (B) of applying a coating fluid capable of forming a transparent resin (12) to at least one side of the prefilm and setting or curing the coating fluid to form a light-diffusing film (10). The process attains prefilm production at a higher production rate than those of conventional processes and thus makes it possible to produce the light-diffusing film (10) with enhanced productivity.</p>
