Abstract:
A screen that displays images as a result of receiving projection light, includes: a plurality of plate components that are optically transparent and are provided apart from each other; a scatterer that is placed in a light scattering space that is formed between the plurality of plate components, and is formed by dispersing a light scattering material in a gas or liquid dispersion medium; a flow path that allows the scatterer to flow through the light scattering space; and a flow device that causes the scatterer to flow through the light scattering space.
