。The three primary color phosphors of red, green, and blue are repeatedly arranged in stripes on the inner surface of the face plate of the picture tube, sandwiching a black guard band, and the phosphors are arranged repeatedly in stripes in a regular relationship with these phosphors. When a surface consisting of an index element is scanned with an electron beam emitted by a single electron gun, a color signal is synthesized with the index signal obtained from the index element, and the electron beam based on the color signal is emitted to a predetermined fluorescence. In a beam index type color television receiver that is designed to impact a light object, there is a horizontal deflection coil that has the characteristics of a barrel magnetic field on the front side near the face plate, which has a bottle cushion magnetic field as a whole in the axial direction, and a horizontal deflection coil that has the characteristics of a barrel magnetic field in the front side near the face plate. The beam has a barrel magnetic field as a whole, but uses a vertical deflection coil that has the characteristics of a bottle cushion magnetic field on the front side, so that the beam spot shape due to astigmatism becomes vertically elongated in the same direction as the phosphor stripe around the screen. Index type color television receiver.
