Abstract
An electron gun for a color cathode ray tube includes a first electrode, a second electrode and a third electrode. A waveform alternating voltage or a static voltage is applied to the first electrode in which three vertical slot type electron beam passing holes are formed. The second electrode is installed at one side of the first electrode in which circular electron beam passing holes are formed. The third electrode is disposed at the other side of the first electrode. A single horizontal slot type electron beam passing hole is formed in the third electrode to which the same dynamic focus voltage as that in the second electrode is applied.
