Abstract
PURPOSE: To raise luminance and to enhance stain resistance by a comparatively simple manufacturing method, by coating a specified screen coating on the roughened face of an absorptive surface material in a projection screen reflecting the image of a TV picture tube.
CONSTITUTION: Absorptive surface material 6 having roughened face to be used as a reflective surface is provided on a substrate 5. 7 Aluminum powder-containing screen coating 8 is coated on this. The solvent of coating 8 is absorbed at once into the inner part without remaining on the surface of material 6, resulting in leaving the aluminum powder on surface 7 and reproducing that pattern with fidelity.
