ABSTRACT:
A shadow mask type color cathode ray tube which has a face panel whose screen face is flattened to more than two times the flatness of the conventional flat panels without reducing the resistance of the glass bulb to outside pressure in spite of its relatively thin glass wall, and has an enhanced reflection characteristic of incident light as well as improved local doming characteristics.
