摘要：
There is provided a light diffusing element made of a thin film capable of realizing low back scattering and a high haze. A light diffusing element according to an embodiment of the invention includes: a first region having a first refractive index n1; a refractive index modulation region having a substantially spherical shell shape and surrounding the first region; and a second region having a second refractive index n2, the second region being positioned on a side of the refractive index modulation region opposite to the first region. The light diffusing element satisfies the following expressions (1) and (2): 0.0006≦Δn/L (1) 10≦(Δn)2×A×B≦100 (2).
