PURPOSE:To enable a metallic film with a high reflectance to be formed by placing a shield plate on the bottom of a pallet on which a panel is to be placed and moving the shield plate only during vapordeposition. CONSTITUTION:At the point when a glass face panel 1 is carried into an aluminum vapordeposition chamber 6b, the opening 12a of a picture-tube carrier pallet 12 is closed with a shield plate 13 to shield the fluorescent screen of a glass face plate 1 or an intermediate film 3 from an evaporation source by means of the shield plate 13. When the vacuum degree of the aluminum vapordeposition chamber 6b is increased up to near a level for the initiation of evaporation, a high electric potential is applied to a resistance heater 7 to increase its temperature. Next, the opening 12a of the paller 12 is opened by moving the shield plate 13 from the shielding position to cause the evaporation source and the fluorescent screen to face each other. Following that, supplying of aluminum wire 9 is started and proper vapordeposition is performed under a high vacuum for a given time. |
