摘要
A color cathode ray tube includes an electron gun having a plurality of electrodes, an electron beam deflection device and a phosphor screen. A deflection defocusing correcting element is located in a deflection magnetic field produced by the deflection device to locally modify the magnetic field in a path of an electron beam and corrects the deflection defocusing of the electron beam corresponding to deflection of the electron beam. The deflection defocusing element includes the magnetic metal plate providing magnetic pole pieces and a non-magnetic metal support for holding the magnetic metal plate in place. The magnetic metal plate and the non-magnetic metal support are laminated or clad one on another, or joined edge-to-edge.
