摘要 |
A shadow mask is arranged in an envelope and opposes a phosphor screen formed on an inner surface of a face plate. The shadow mask includes a plurality of mask pieces arranged in series. Each of the mask pieces has effective portions in which a number of electron beam passage apertures are formed. A plurality of mask frames supporting the respective mask pieces are fixed to the inner surface of the face plate. A plurality of stages are provided on the inner surface of the face plate. Each of the stages has a first end in contact with the inner surface of the face plate and a second end in contact with one of the mask piece, so as to define a distance between each of the mask pieces and the phosphor screen and to apply a tensile force to the mask piece.
