Further, as a feature of this device, fine particles of transparent hard resin are spray-painted on the surface of the transparent resin film T to form a coating layer 9 having a thickness of about 0.5 μm and having fine irregularities on the surface. . According to this configuration, since the surface of the coating layer 9 has fine irregularities, external light can be scattered, and the display is not difficult to see due to reflection of external light as in the past, and the display is easy to see. can be taken as a thing.

Furthermore, since the coating layer 9 is made of hard resin particles, it is less likely to be scratched and has a longer service life. Effects of the Invention As described above, according to the present invention, even when a switch is added to the surface of a cathode ray tube using a transparent resin film and a transparent electrode, the display does not become difficult to see due to reflection of external light.
Moreover, it is possible to realize a product that is hard to get scratched and has a long life.
