A CATHODE-RAY TUBE HAS, AS AN ANTIREFLECTION FILM, AN OPTICAL INTERFERING FILM (15) HAVING AT LEAST TWO LAYERS. THE OPTICAL INTERFERING FILM (15) HAS AN AVERAGE ANGLE ( )A OF INCLINATION OF 0.1° TO 0.5°AND AN AVERAGE PEAK GAP SM OF 10 µM TO 50 µM. THIS OPTICAL INTERFERING FILM IS FORMED BY MAINTAINING THE TEMPERATURE OF THE FACEPLATE (1) AT 20 TO 50°, SETTING THE FLOW RATES OF THE OPTICAL INTERFERING FILM FORMING SOLUTION AND AIR FROM AN AIR SPRAY NOZZLE TO 10 TO 30 CC/MIN AND 80 TO 140 1/MIN, RESPECTIVELY, AND SETTING THE SCANNING SPEED OF THE AIR SPRAY NOZZLE TO 250 TO 750 MM/SEC, AND BY USING OPTICAL INTERFERING FILM FORMING SOLUTIONS EACH CONTAINING 1 TO 5 WTOF A SOLID SUBSTANCE AND 10 TO 30OF AN ORGANIC SOLVENT HAVING A BOILING POINT OF 120°C OR MORE.
