PROBLEM TO BE SOLVED: To provide a screen for always obtaining high contrast projection images. SOLUTION: The screen 100 includes a reflection layer 106R, a reflection layer 106G, a reflection layer 106B and a base substance 101 in order from a side on which light is incident. The reflection layers 106R, 106G and 106B reflect R light being light of a specific wavelength region, G light and B light to transmit external light being light of the other wavelength region different from the specific wavelength region.
