Abstract
PURPOSE:To ensure that electric conductivity is complete and that productivity as well as quality are improved by a method wherein an extension, which is the one extended on almost the same plane as that of a skirt on the side of a fluorescent film surface formed on the inside surface of a panel opening, supplied with formed on a metal pin. CONSTITUTION:A metal pin 10 consists of a pin 10a, and an extension 10b extended from the side of the pin and the metal pin 10 has been buried in such a way that the upper surface of the extension 10b is almost equal to that of a skirt portion 4a, besides, the extension 10b is located close to a fluorescent film 7. Accordingly, by coating a black matrit film 6 and the fluorescent film 7 with an evaporated metal film 8, the evaporated metal film is joined directly onto the extension 10b of the metal pin 10 at the end of the evaporated metal film 8m. consequently, conductivity between the evaporated metal film 8 and the metal pin 10, that is, between the fluorescent film 7 and a shadow mask 1, is accomplished. For this reason, faulty conductivity is eliminated, while complete conductivity is accomplished.
