Abstract: PROBLEM TO BE SOLVED: To provide a phosphor screen having flat and smooth surface on which an image data can be recorded clearly with high sensitivity. SOLUTION: A flat and smooth sheet 12 is coated with phosphor in liquid state and laminated under adhesive state without bonding. The phosphor layer 21 is then hardened with the sheet 12 being set on the underside and a board 30 is bonded to the exposed surface 36. The sheet 12 laminated on the phosphor layer 21 is then removed to finish a smooth exposed surface. It is coated, as required, with a transparent protective layer. Since phosphor particles are collected on the flat and smooth surface and no particle project from the surface, the screen is useful for recording a data clearly with high sensitivity.
