Zusammenfassung:An information display system having acute-angled diffusion characteristics configured to display an image to inside or outside of a space via a transparent projected member, the information display system including an image projection apparatus, a transparent sheet provided on an inner surface of a display region set on a part of the projected member; and a light direction changing unit that directs a direction of image light toward the transparent sheet of the display region, the image projection apparatus including an image light characteristic converting unit, and an image light control film that restricts an emission direction of the image light being provided on an upper surface of the image projection apparatus, so that the image light is not directly delivered to an observer and the image light reflected by the transparent sheet is recognized by the observer.
