Abstract
Electron gun in a color cathode ray tube including a separate plate electrode having a thickness thicker than a focusing electrode or an anode, a smooth outer circumference of a rim part, and single electron beam pass through hole for passing of three electron beam in common each fitted to opposite edges of the focusing electrode and the anode, thereby preventing deformation of the plate electrodes, enlarging diameters of the electron beam pass through holes, to allow formation of accurate large sized main focusing electrostatic lens, improving focusing onto a screen, and preventing occurrence of discharge between the focusing electrode and the anode.
