Abstract

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.
