ABSTRACT:
Disclosed are a cathode ray tube and a funnel therefore. An anode button is installed on the funnel to meet the condition of 2.8≦T, in which T is a B/A ratio, A is a distance on a central axis of the funnel between a seal edge face of the funnel, which abuts a panel, and the anode button, and B is a distance on the central axis of the funnel between the anode button and a neck seal of the funnel, which is positioned at the opposite side of the seal edge face in the funnel. According to this invention, it is possible to prevent mechanical interference and electrical interference, such as distortion of deflection magnetic field, caused depending on the installation position of the anode button on the funnel.
