行な段部を形成したこ ？特徴とする陰極線管。A plurality of phosphors with different luminescent colors are sequentially and repeatedly formed in stripes on the inner surface of the face of the bulb, and a metal back film is laminated on the phosphor stripes, and a metal back film is formed on the metal back film or on the peripheral edge of the metal back film. A stripe of the optical index phosphor is formed, and an electron gun is housed in the neck part to supply an electron beam to the phosphor stripe and cause it to emit light.
In a device in which a sensor for detecting an optical index signal is arranged at the position of the light transmission window on the outer periphery of the funnel part, a stepped part substantially parallel to the face part is formed at the position of the light transmission window on the inner surface of the funnel part of the bulb. Characteristic cathode ray tube.
