Abstract
A light-diffusion member includes a substrate having light transparency, a plurality of light-diffusion parts formed on one surface of the substrate, and a light-absorbing layer formed in a region other than a region where the light-diffusion parts are formed, among the one surface of the substrate. Each light-diffusion part includes a light-emission end surface on the side of the substrate and a light-incident end surface of an area larger than an area of the light-emission end surface on a side opposite to the side of the substrate. The height from the light-incident end surface of the light-diffusion part to the light-emission end surface thereof is larger than the thickness of the light-absorbing layer. The plurality of light-diffusion parts are randomly arranged on the one surface of the substrate.
