ABSTRACT OF THE DISCLOSURE A flat cathode ray tube is disclosed in which the deflection of an electron beam in the direction which requires a large deflection angle is carried out by the electromagnetic deflection, while the deflection of the electron beam in the direction which requires a small deflection angle is carried out by electrostatic deflection. Further, in the evacuated envelope of the flat cathode ray tube, there is located a high magnetic permeability body to concentrate the magnetic flux on the electron beam necessary for the electromagnetic deflection. In a certain case, a magnetic material body with the electrical conductivity is used as the high magnetic permeability body so as to provide it with the function of serving as an electrode plate for the electrostatic deflection of the electron beam.
