PROBLEM TO BE SOLVED: To provide a transmission projection screen excellent in color clarity of a transmission projection image in a bright environment for use and in a hot spot deterrent effect and having heat insulation properties, which is used as a projection screen for a show window and also a heat insulation blind.SOLUTION: A light transmissive resin sheet containing light diffusive particles in thermoplastic resin contains a metal composite oxide, and is dyed to have Munsell lightness 0-4 (Munsell color system). Therefore, a transmission projection screen expresses an average reflectance of 10% or less in a visible light wavelength region from 400 to 750 nm and an average reflectance of 25% or greater in a near infrared ray wavelength region from 750 to 1200 nm. |
