A color cathode-ray tube comprises an envelope having rectangular flat face and rear plates opposing each other. A phosphor screen is formed on an inner surface of the face plate. Mask support members are mounted on an inner surface of the rear plate. A shadow mask is arranged in the envelope and supported by the mask support members to face the phosphor screen at a predetermined distance. A plurality of positioning posts are fixed on the inner surface of the rear plate and extend toward the face plate. A plurality of positioning pins extend from the inner surface of the face plate and engage the positioning posts so as to position the face plate at a predetermined position with respect to the rear plate. The shadow mask has setting openings through which the positioning posts extend so as to position the shadow mask at a predetermined position with respect to the rear plate.
A method of manufacturing a color cathode-ray tube comprising an envelope having a substantially flat face plate, a side wall extending in a direction substantially perpendicular to a peripheral portion of the face plate, a substantially flat rear plate opposing the face plate, and a phosphor screen formed on an inner surface of the face plate, a shadow mask arranged in the envelope and having a plurality of election beam passage apertures, and mask support means provided at the rear plate, for supporting the shadow mask in a position to face the phosphor screen at a predetermined distance, said method comprising the steps of:
A method of manufacturing a color cathode-ray tube comprising an envelope having a substantially flat face plate, a side wall extending in a direction substantially perpendicular to a peripheral portion of said face plate, a substantially flat rear plate opposing the face plate, and a phosphor screen formed on an inner surface of the face plate, a shadow mask arranged in the envelope and having a plurality of electron beam passage apertures, and mask support means provided at the rear plate, for supporting the shadow mask to face the phosphor screen at a predetermined distance, said method comprising the steps of:
