Fluorescent light emission screen

Abstract

Abstract PURPOSE:To improve the contrast by placing a glass or a fluorescent particle layer where a light absorption subsistance is arranged selectively and perpendicularly against a face glass between a fluorescent particle layer and the face glass. CONSTITUTION:A layer composed of a glass 3 where a light absorption subsistance 2 is arranged perpendicularly against a face glass 1 is coated on the inner face of said face glass 1, then a fluorescent particle layer 4 composed of fluorescent particles 4 which emit the light of predetermined color and a metal-back layer 5 made of such as aluminium are coated on it. Fluorescent particles can be employed in place of the glass particle 3.
