A light diffusion control member includes a first light diffusion control layer and a second light diffusion control layer. The first light diffusion control layer and the second light diffusion control layer each has a regular internal structure that includes a plurality of regions having a relatively high refractive index in a region having a relatively low refractive index. The first light diffusion control layer and the second light diffusion control layer are laminated so that an angle between two respective vectors determined based on the regular internal structure in the first light diffusion control layer and the second light diffusion control layer is more than 0° and 90° or less.
