記載の陰極線管。[Claims for Utility Model Registration] 1. An electron gun unit that emits an electron beam in response to an input video signal, a fluorescent means that emits light by the electron beam from the electron gun unit, and a glass on which the fluorescent means is arranged on the inner surface. a rear panel that houses the electron gun unit together with the front panel; and an external drawer that is fitted into the joint between the front panel and the rear panel and that is electrically connected to the electron gun unit. A cathode ray tube having a terminal, wherein the front panel and the rear panel are joined with a glass frit having a volume resistivity of 10 7 Ωcm or more at 250°C, and the external lead terminal is connected to the inside of the joint of the front panel. A cathode ray tube that penetrates at a distance of 300 μm or more from the surface. 2. The front panel is made of glass having a soda lime silica composition, and at least the image display portion is made of K.
The cathode ray tube according to claim 1, which contains more K ions than the interior thereof and has reduced coloration due to electron beam irradiation through ion exchange treatment in a molten salt containing ions.
