A color CRT having a body portion coupled to a panel, a neck portion in which an electron gun is installed and a yoke portion formed to be connected between the body portion and the neck portion and in which a deflection coil is mounted, wherein an outer face of the yoke portion satisfies a relational expression of 0.6<.DELTA.HV/L<0.71, of which `L` indicates a diagonal length of an outer face of the yoke portion, `H` indicates a long axis length of the outer face of the yoke portion, `V` indicates a short axis length of the outer face of the yoke portion, .DELTA.H indicates a difference between the diagonal length `L` and the long axis length `H`, .DELTA.V indicates a difference between the diagonal length `L` and the short axis length `V`, .DELTA.HV indicates the sum of .DELTA.H and .DELTA.V. The funnel of a color CRT in accordance with the present invention is constructed such that the design range of the yoke portion is optimized when the screen ratio is about 16:9, so that the high luminance and a high frequency are satisfied, the deflection power is reduced, and the leakage magnetic field is reduced.

Una CRT del color que tiene una porción del cuerpo juntada a un panel, una porción del cuello en la cual un arma de electrón está instalado y una porción del yugo se forma para ser conectada entre la porción del cuerpo y la porción del cuello y en cuál se monta una bobina de la desviación, en donde una cara externa de la porción del yugo satisface una expresión emparentada de 0.6
