Battery module

In a color cathode ray tube apparatus having an electron gun assembly for emitting three electron beams disposed in one line, the electron gun assembly has at least first, second, and third electrodes G5, G7, and G9 applied with a voltage which changes in synchronization with deflection of electron beams. The first electrode and an electrode G4 adjacent thereto form first eccentric lenses for deflecting a pair of side beams in a direction in which the side beams extend to be close to the center beam. The second electrode and an electrode G6 adjacent thereto form second eccentric lenses for deflecting the side beams in a direction in which the side beams extend to be apart from the center beam. The third electrode and an electrode G8 adjacent thereto form third eccentric lenses for deflecting the side beams in a direction in which the side beams extend to be close to the center beam. An electron lens common to the three electron beams is formed between the second and third eccentric lenses. It is possible to realize a color cathode ray tube apparatus which displays a high quality image over the entire area of the screen by means of these electron lenses.
