PROBLEM TO BE SOLVED: To provide screen texture which enables superior measures against environment in use and environmental contamination in burning after use, is nearly free of formation of interference fringes, and makes a picture sharp and easy to see. SOLUTION: The screen texture A on which a picture is projected is made of light-shielding stain woven cloth 12 using polyester yarns 11, which are made flameproof and impregnated with titanium dioxide. When the picture is projected, light is not blocked and no interference fringe is formed since the polyester yarns are used; and the yarns contain titanium dioxide, which reacts to ultraviolet rays to display antibacterial and deodorant effects.
