ABSTRACT:
Human bodies are shielded from an alternating electric field radiated from a deflection yoke of a cathode-ray tube device to prevent the alternating electric field from adversely affecting the human bodies. For an alternating electric field traveling forward in the direction of a tube axis 28 of a cathode-ray tube, a cone section 1b is formed with a conductive film 17 for shielding an electric field and/or a face panel 2 is formed with a transparent conductive film 21 for shielding an electric field and the transparent conductive film 21 is grounded or an optimum potential is given only to the transparent conductive film 21 for shielding an electric field.
