- the protective layer 18 is formed by Mg ⁇ has been described as an example.
- the present invention also includes other materials such as ITO and silver for forming the display electrode 16. Starting with the film, the substrate 13 Similar effects can be obtained when the film is formed while holding at 1.
- an electron beam evaporation method is shown as an example of a film forming method.
- the electron beam evaporation method not only the electron beam evaporation method, but also a method of ion plating using a hollow sword method and sputtering under reduced pressure. The same effect can be obtained in the film forming method performed.
- the present invention is capable of suppressing the deposition of a film-forming material on the non-film-forming surface of a plasma display panel substrate, and is a method for manufacturing a plasma display panel known as a large-screen, thin, and lightweight display device.
- a plasma display panel known as a large-screen, thin, and lightweight display device.
