Abstract
A cathode-ray tube for preventing electrification and shielding electromagnetic waves and manufacturing method thereof are provided. A cathode ray tube of the invention includes a transparent conductive film and a transparent insulating protective film, an electrode formed on at least a part of an inactive screen and on sides of the panel portion before the transparent conductive film and the transparent insulating protective film are coated; and a conductive tape coated with a conductive adhesive, electrically connecting the electrode and an, explosive-proof band. According to this invention, a panel of the cathode ray tube is grounded by an electrode being in direct contact with a transparent conductive film, which provides more effective grounding than that through a protective film. At the same time, the cathode ray tube panel can effectively suppresses static electricity buildup and blocks electromagnetic waves by providing a path to ground through which excess electric charge generated on the surface of a cathode-ray tube can easily flow off, while preventing damage to an electrode.
