摘要
A cathode ray tube including an electron gun including a cathode and a plurality of electrodes and for generating an electron beam, a phosphor screen and an electron beam deflection device. The cathode ray tube includes a deflection-defocusing correcting member having laminated nonmagnetic and magnetic materials disposed in a deflection magnetic field produced by the electron beam deflection device for establishing at least one non-uniform magnetic field. The magnetic materials are disposed at positions with respect to a path of the electron beam where a magnetic flux density of said deflection magnetic field is more than five per cent of a maximum magnetic flux density of the deflection magnetic field.
