Abstract
A color cathode ray tube capable of improving the luminance attenuation characteristic and the explosion-proof characteristic through an improved shape of a panel is disclosed. In an equation F=Rdo/(Sd H 1.767), F>21, Tc/CFT≦1.35, and Rdi>(Ryi or Rxi) are satisfied, wherein Sd is a length of a diagonal effective picture of the panel, Rdo is a curvature radius of a diagonal outer surface, Ryo is a curvature radius of a vertical outer surface, Rxi, Ryi and Rdi are a horizontal, vertically and diagonal curvature radius, respectively, CFT is a thickness of a center portion, Tc is a thickness of a diagonal end of the effective surface, F is a planarizing rate of the outer curvature.
