Publication number: 20040056603Abstract: An electron gun of the present invention is provided with focus electrodes G5A, G5B, an anode electrode G6 disposed on a side subsequent to the focus electrodes, and a prior electrode G4 disposed on a side prior to and next to the focus electrode G5A, G5B, as shown in FIG. 14, for example. To the prior electrode G4 an intermediate potential between an anode potential and a focus potential is supplied through a resistor 35. Therefore, electron beams emitted from cathodes are accelerated at the early stage in the prior electrode G4, and repulsion between the electron beams is restrained, so that the increase in a beam spot diameter on a fluorescent screen is restrained. Further, since a voltage dividing terminal is positioned distant from the high-voltage side, discharge within the cathode-ray tube is restrained. A cathode-ray tube of the present invention includes the above electron gun.Type: ApplicationFiled: July 2, 2003Publication date: March 25, 2004Inventor: Norifumi Kikuchi
