成したことを特徴とする陰極線管。 A fluorescent film is formed on the inner surface of the face of the bulb, polymerized with the fluorescent film, and a metal back layer is formed on the inner peripheral surface of the funnel, and an electron gun is housed therein. A cathode ray tube that deflects an electron beam emitted by a gun and causes a fluorescent film to emit light, characterized in that fine particles are interposed between the inner surface of the funnel part and the metal back layer, where the deflecting magnetic field mainly interlinks, to form irregularities. Cathode ray tube.
