PROBLEM TO BE SOLVED: To realize a screen for projection on which a high-contrast picture is displayed even under bright light and which has a specified angle of visibility. SOLUTION: The screen for projection is constituted by forming a reflection diffusing layer 22 incorporating light reflective particles 21 having high reflection characteristic to the light of the wavelength regions of three primary colors and high absorption characteristic at least to the light of a visible wavelength region other than the wavelength regions of three primary colors on base material 23, and a light diffusion control plate 24 is provided on the surface of the diffusing layer 22, then a black light absorption layer 25 is provided on the back of the base material 23.
