The internal structure includes a plurality of regions having a relatively high refractive index in a region having a relatively low refractive index. The laminate further includes an ultraviolet absorbing layer located further on the external light incident side than the light diffusion control film. The light diffusion control film contains a weakly basic hindered amine-based compound having a carbonate skeleton.
