Abstract:
A transparent screen is a transparent screen for diffusing image light projected from a projector and displaying an image by transmitting part of incident light rectilinearly and diffusing the other part of the incident light. The transparent screen includes a first base material that is transparent, a diffusion member, a second base material that is transparent, and a plurality of light absorption materials. The diffusion member is disposed within a first base material and diffuses the image light. The second base material is disposed on an opposite side of the first base material from the projector. The plurality of light absorption materials is disposed within the second base material and is arranged parallel to each other along an arrangement direction parallel to a principal plane of the second base material.
