And upper and lower horizontal beams extending a predetermined length to the cathode side at upper and lower portions of the electron beam passing holes formed on the incident side of the dynamic focus electrode, and both edges of the electron beam passing holes formed on the exit side of the focus electrode corresponding to the horizontal blades. The vertical braid and the horizontal quadrilateral holes are formed in the upper and lower portions, respectively, so that the horizontal braid is inserted into the horizontal quadrilateral holes, and between the focus electrode and the dynamic focus electrode during deflection of the electron beam by deflection yoke. Quadrupole lens formed on the deflection of the yoke By enhancing the uniform magnetic field, so it can improve the astigmatic aberration and the focus characteristics can be manufactured of a cathode ray tube having a clear image and have the advantage of completely eliminating the quality deterioration due to the mounting accuracy between the electrodes.
