Summary:PROBLEM TO BE SOLVED: To provide a screen which can improve the contrast of videos by making a surface to be displayed with the videos visible substantially gray or black. SOLUTION: The screen 10 has a mat layer 12 which is disposed at a sheet 11 and is used to diffuse and reflect light and a contrast regulating layer 15 which consists of three kinds of colored beads 15A to 15C fastened to the mat layer 12 by an adhesive layer 14. The colored beads 15A to 15C are respectively colored to any among three kinds of chromatic colors (cyan color, magenta color and yellow color) are respectively disposed to scatter on the surface of the mat layer 12 at such quantities at which these chromatic colors are mingled with each other and appear achromatic approximate to gray color when an observer observes the screen 10 from remote in such a manner that the white light is made incident as external light thereon. The projected light from a projector transmits the colored beads 15A to 15C and is reflected by the front surface of the mat layer 12.
