CATHODE RAY TUBE DEVICE

PROBLEM TO BE SOLVED: To effectively restrain a leakage electric fiels, by forming a fixture of an insulating part contacting a deviation device, and of a conductive part non-contacting the deviation device and led to earth electric potential. SOLUTION: A conductive part is provided on a fixture 23 composed of an insulator to be inserted between the large-diameter part 4 outer surface of a funnel 2, and the large-diameter part 4 inner side of a deviation device 6, in order to position to fix the large diameter part 4 of the deviation device 6. When one end part of the conductive part contacts to electrically connect to a conductive coat 8 formed on the large diameter part 4 outer surface, and is earthed; the conductive part 25 of the fixture 23, positioned in the large- diameter part 4 inner side of the deviation device 6, becomes a zero-bolt equipotential surface, thereby a shield surface, having an electric field shielding effect, can be formed on the large-diameter part 4 front surface. This can restrain a leakage electric field, from the deviation device 6, leaked in the front surface direction of a cathode-ray tube.
