An electron gun for a cathode ray tube includes a triode portion including cathodes,
a first electrode, and a second electrode arranged with predetermined gaps therebetween.
A plurality of electrodes arranged in sequence starting from a position adjacent
to the second electrode. The electrodes receiving a voltage, for example, a constant
voltage or a dynamic voltage. The dynamic voltage is synchronized with a deflection
signal of electron beams. An anode electrode is positioned having a predetermined
gap between the electrode arranged farthest from the cathodes. A support maintains
the electrodes at predetermined intervals. One of the electrodes is a multiple-element
electrode that includes two interconnected sub-electrodes. Gaps are formed between
portions the sub-electrodes of the multiple-element electrode.
