Abstract
A screen includes a light diffusion layer in which microcapsules, each having therein a light diffusion liquid that scatters light for displaying a video image, are planarly arranged. The light diffusion layer is fixed to a supporting sheet by a binder material. On a surface of the supporting sheet, a Fresnel lens is formed. A light diffusion plate is made up of the light diffusion layer and the supporting sheet. The screen is made up of the light diffusion plate and a light diffusion plate. Scattering distribution of a scattered wave of light that passes through the light diffusion layer temporally changes.
