説明する。Generally, in the operation of an in-line color picture tube,
A self-convergence type deflection yoke is used. When such a deflection yoke is used, a complicated convergence mechanism is not required, but the horizontal deflection magnetic field is distorted into a bottle-cushion shape and the vertical deflection magnetic field is distorted into a barrel-shape, so bottle-cushion distortion is likely to occur in the raster. Therefore, the distortion is corrected by superimposing a correction current on the deflection direct current. Recently, a deflection yoke with a special winding structure has been used to distort the horizontal and vertical deflection magnetic field distribution into a strong barrel shape on the electron gun side and a strong bottle cushion shape on the phosphor film side. , the horizontal deflection magnetic field as a whole is distorted into a bottle cushion shape, and the vertical deflection magnetic field as a whole is distorted into a barrel shape. In this case, the raster bottle cushion is distorted without superimposing a correction current on the deflection current. shape distortion can be corrected. However, the influence of deflection aberration due to comatic aberration becomes large, and as shown in FIG.
It has the disadvantage of being larger in the horizontal direction and smaller in the vertical direction. The present invention provides a color picture tube device in which the size of the green raster G can be made close to each size of the red raster R and the blue raster B while using such a self-convergence type deflection yoke. The color picture tube device will be described in detail with reference to embodiments shown in the drawings.

It is distorted into a strong barrel shape on the tllll side, and then into a strong bottle cushion shape on the phosphor film side, and furthermore, the water/dough deflection 1 circle is made pink as a whole, and it is divided into a round shape. , and as a deflection yoke that distorts the vertical deflection magnetic field as a whole into a barrel-like distribution, the angle of the vertical toroidal coil with respect to the ferrite core is wider on the electron gun side than on the screen surface side. This causes a strong barrel-like distortion on the electron gun side. i [In addition to the spiral winding method, the winding angle on the phosphor film side of the electron gun should be narrowed so that the VC1 vertical deflection magnetic field distribution has an overall pink non-yon tendency. A method of creating a barrel distortion by providing a magnetic material C on the side, as described above, by providing an arm-shaped magnetic +<1 piece on the phosphor film side and utilizing the leakage magnetic flux.
