Abstract
An electron gun for a color cathode ray tube includes a cathode, a control electrode and a screen electrode all together for forming a triode section, a plurality of focus electrodes for forming an auxiliary lens section and a final accelerating electrode disposed adjacent to the focus electrodes is stronger than that of the main lens section, the electron beams cross in from of said the main lens section. The electron gun allows uniform electron beam spots to be obtained all over a fluorescent film by reducing spherical aberration of lenses.
