Abstract:
A display system includes: a screen in which, in an area on which invisible light is incident, a scattering state where visible light is scattered and a transmission state where visible light is transmitted are switched; an image projection system to project an image of the visible light onto the screen; and an invisible light projection system to project the invisible light onto the screen and to cause an area of the screen onto which a desired portion of the image is projected to have the scattering state.
