摘要： A focus electrode is constituted by a first type of focus electrode group to which a first focus voltage is applied, and a second type of focus electrode group to which a second focus voltage is applied. Between the first type of focus electrode group and the second type of focus electrode group are formed a lens at least having a lens action for correcting the field curvature and an electrostatic quadrupole lens. The center axes of the outer electron beam passage holes in the first type of focus electrode forming the lens at least having a lens action for correcting the field curvature are deviated on a horizontal plane from the center axes of the outer electron beam passage holes in the second type of focus electrode. The electrostatic quadrupole lens produces dissimilar intensities for the outer electron beams and for the center electron beam. Therefore, the outer electron beam passage holes work to deflect the outer electron beams toward the center electron beam with an increase in the deflecting amount of the electron beams, and a favorable resolution is obtained on the whole screen of the cathode-ray tube.

The main lens includes a final lens formed between the accelerating electrode and an electrode opposing the accelerating electrode and configured so that outer electron beats are deflected toward a trajectory of a center electron beam and a lens strength of the final lens weakens with beam deflection The electron gun also has at least one multipole lens located between the final lens and the beam forming region and configured so as to change a cross sectional shape of the electron beams with beam deflection, and a lens formed between a pair of electrodes located between the final lens and the beam forming region and having axially spaced opposing surfaces each having opposing center beam apertures and opposing outer beam apertures. The centers of the opposing outer beam apertures in the opposing surfaces are displaced from each other in a direction perpendicular to the electron gun axis. The lens formed between the pair of electrodes focuses the electron beams in both horizontal and vertical directions and changes a focusing strength thereof with beam deflection and deflects the outer electron beams toward or away from the center electron beam with beam deflection.
