ABSTRACT:
A transparent conductive film is formed on an outer surface of a face portion of a face panel and a phosphor screen is formed on an inner surface thereof. A conductive explosion proof band is wound around an outer periphery of a skirt portion of the face panel and the explosion proof band has a grounding potential. A conductive tape is attached along a long side of the face panel and electrically connects the transparent conductive film with the explosion proof band. A compensating electrode extending along a side of the face panel is attached to an upper side of the skirt portion and disposed on a side opposite to the conductive tape with respect to the explosion proof band. An inverse voltage applying portion applies a voltage having a waveform of a polarity inverse to that of the deflection voltage applied to a deflection device to the compensating electrode so as to generate an electric field for canceling an alternating electric field generated from the deflection device.
