摘要： To provide a light diffusion film that contributes lightweight with reduction in thickness, a planar light source element utilizing the light diffusion film, and a liquid crystal display device utilizing the light diffusion film and/or the planar light source element. A light diffusion film (25) having a plurality of projections (23) of a specific shape is at least partly formed from a composition containing a mixture of a photocurable compound and a particulate material. A light guide plate (22), provided with one or more light sources (21) at one side face thereof, is bonded to vertexes of the projections (23) to provide a planar light source element, which is thin and lightweight and capable of emitting non-glaring light uniformly from the entire surface thereof.
