Abstract
A light diffusion member includes a light transmissive substrate, a plurality of light diffusion sections formed on one surface of the substrate, a light shielding layer formed in a region other than formation regions of the light diffusion sections on the one surface of the substrate, and light scattering bodies. The light diffusion sections have a light emitting end surface on the substrate side and a light incident end surface having an area greater than an area of the light emitting end surface on a side opposite to the substrate side. A height from the light incident end surface to the light emitting end surface of each of the light diffusion sections is greater than a thickness of the light shielding layer. The light scattering bodies are disposed further on a light emitting side than the light diffusion sections.
