陰極線管。 Index stripes that generate index signals are formed at predetermined array pitches on the inner surface of the bulb, and electrons are transferred to the phosphor screen, which is formed by alternately forming phosphor stripes that emit light in three primary colors and light absorption layers between each index stripe. In a beam-indexed cathode ray tube in which a beam is irradiated, the phosphor screen is observed from the irradiated side, and an index signal is extracted from the back side of the phosphor screen, a light absorption layer is formed on the index stripe by a dry method. A beam index type cathode ray tube characterized by a laminated structure.
