Abstract
A reflective screen (1) displaying an image by projected light, comprises: a transparent substrate (10); a light-absorption layer (20) provided on the transparent substrate, the light-absorption layer reflecting the projected light; and a scattering layer (30) provided on the light-absorption layer, the scattering layer scattering the projected light, wherein the light-absorption layer has 30-90% transmittance with respect to visible light, and the scattering layer contains a light-scatterer (31) consisting of diamond particles and/or metallic inorganic particles.
Claims11
A reflective screen displaying an image by projected light, the reflective screen comprising:
- a transparent substrate;
- a light-absorption layer provided in direct contact with the transparent substrate with or without an adhesive, the light-absorption layer absorbing visible light;
- and
- a scattering layer provided in direct contact with the light-absorption layer with or without an adhesive, the scattering layer scattering the projected light,
- wherein
- the light-absorption layer has 30-90% transmittance with respect to visible light, and
- the scattering layer contains a light-scattering medium consisting of diamond particles and/or metallic inorganic particles.
A reflective screen displaying an image by projected light, the reflective screen comprising:
- a colored substrate having 30-90% transmittance with respect to visible light;
- and
- a scattering layer provided on the colored substrate, the scattering layer scattering the projected light,
- wherein the scattering layer contains a light-scattering medium consisting of diamond particles or diamond particles and metallic inorganic particles.
A sheet for a reflective screen displaying an image by projected light, the sheet for the reflective screen comprising:
- a transparent sheet consisting of transparent polymer resin, the transparent sheet having flexibility;
- a light-absorption layer provided in direct contact with the transparent substrate with or without an adhesive, the light-absorption layer absorbing visible light;
- and
- a scattering layer provided in direct contact with the light-absorption layer with or without an adhesive, the scattering layer scattering the projected light,
- wherein
- the light-absorption layer has 30-90% transmittance with respect to visible light, and
- the scattering layer contains a light-scattering medium consisting of diamond particles and/or metallic inorganic particles.
