Abstract: PURPOSE:To eliminate misconvergence which means that a screen pictured by a center beam at both right and left end portions of the screen slips to the left in relation to a screen pictured by a pair of side beams by installing a three dimensional portion at the annular portion of a magnetic field control element. CONSTITUTION:A magnetic field control element 30 made of a magnetic substance with high magnetic permeability is arranged on the bottom of the convergence cup 2 of an electron gun in such a way that 3 electron-beam passing holes 3B, 3G, 3R are individually surrounded by the element 30, while facing to 3 cathodes respectively. The element 30 is constituted of an annular portion 31 and a three dimensional portion 32, and the pair of three dimensional portions 32 have a plane portion 32a and a side wall portion 32b. When an electron beam scans from the left to the right on a screen, the magnetic field generated in the central part of the screen acts on each electron bean to the same extent because of a projecting form of the pair of 3 dimensional portions 32. The quantity of right drift of a center beam is, therefore, equalized to the quantities of drift of a pair of side beams, so that it is possible to eliminate the right drift of a raster drawn by a center beam on a previously generated screen.
