Abstract
A cathode ray tube with a central tube axis Z includes a panel with an inner phosphor screen and a rear portion. The panel has a substantially rectangular effective screen portion with two long sides in a horizontal axis direction, two short sides in a vertical axis direction and four edges in a diagonal axis direction. A funnel is connected to the rear portion of the panel. The funnel sequentially has a body with a large-sized end and a small-sized end, and a cone portion with a large-sized end and a small-sized end. The cone portion has a thickness Th in the horizontal axis direction, a thickness Tv in the vertical axis direction and a thickness Td in the diagonal axis direction. The horizontal thickness Th, the vertical thickness Tv and the diagonal thickness Td of the cone portion of the funnel in the tube axis Z direction satisfy the following condition: Th(z)=Tv(z)>Td(z).
