ネルピン４を経由する方法は同様である。As shown in FIG. 4, in the color picture tube, an interior graphite film 2 is formed on the inner surface of a panel 10, and an A-e film 3 for preventing the generation of K secondary electrons is formed on the interior graphite film 2. A graphite film (hereinafter referred to as pin graphite film) 5 that connects to the panel pins 4 is applied onto the AA film 3. Although there are various shapes of the pin graphite film 5 depending on the workability and mass productivity, the method of passing through the panel pin 4 is the same.

がある。In addition, the coating work of the pin graphite film 5 is carried out both by self-employed workers and by manual workers, and although it is possible to apply the coating by a certain amount of work in the case of automation, high voltage conduction defects may occur due to irregularities in the work when it is done manually. There are problems with quality stabilization.

れる。In addition, the above purpose is to form an internal graphite m-t on the inner surface of the panel, then arrange a shielding plate in the shape of a pin graphite film coating on the panel pin part, and remove the pin graphite film coated part corresponding to the shielding plate by vapor deposition. A. ．． This is achieved by depositing an e-film and then applying a pin graphite film that establishes conduction with the panel pins on the pin graphite film application area.

ピン黒鉛膜塗布部分６が形成される。Next, a method for forming the pin graphite film coated portion 6 shown in FIG. 1 will be explained. When forming the AA film 3 on the internal graphite film 2, as shown in FIG.
A shielding plate 7 having the same shape as the K-pin graphite film coating shape is arranged, and A. ．． Form e-film 3. In this case, the A-e vapor deposited from the A-e vapor deposition source 8 is deposited on the interior graphite film 2 except for the shielding plate 7, and the pin graphite film coated portion 6 is formed as shown in FIG. It is formed.
このように、ピン黒鉛膜塗布部分６にはＡＡ膜３が形成
