<p>Magnets (56a, 56b, 110a, 110b, 112a, 112b) for applying a pincushion type magnetic field to three electron beams emitted from an electron gun assembly (42) is arranged between the deflection device and the lens unit of the electron gun assembly. The pincushion type stationary magnetic field produced by the magnets correct deflection aberrations of the electron beams due to the magnetic field of the deflection device and improves the focusing characteristic on the periphery of a screen (46).</p> |
