Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a metal-backed phosphor screen, capable of preventing an electron emitter and a phosphor screen from being damaged or deteriorated due to electric discharge.
SOLUTION: The method for forming metal-backed phosphor screen comprises forming a layer (dissolution or oxidation layer) containing a material for dissolution or oxidation a metal layer in a predetermined area on the phosphor screen, and then forming a metal layer thereon. By performing heating process such as baking, the metal layer located directly over the dissolution or oxidation layer is dissolved and eliminated, or converted into an oxidant with high electricity resistance, thus achieving a metal-backed layer electrically segmented into a predetermined pattern.
