Abstract
Images are displayed on an image display screen by projection light for displaying images onto the image display screen. The image display screen is integrally formed with diffusion/reflective parts, which reflect the projection light on a side of the image display screen on which the projection light is incident, and diffusion/transmissive parts, which transmit the projection light in a direction in which the projection light is incident. A first image, which is visible from a side on which the projection light is incident on the image display screen, is displayed by projecting front side projection light onto the diffusion/reflective parts, and a second image, that is visible from a back side of the image display screen, is displayed by projecting back side projection light onto the diffusion/transmissive parts. By doing so, an image display system and method with an improved advertising effect can be provided at low cost.
