Abstract
A color cathode-ray tube is provided with constitution between a shadow mask electrode and a frame body such that difference of expansion and contraction between the shadow mask electrode and the frame body according to heat brings no-picture quality deterioration with practical cost. The shadow mask electrode made of metal whose thermal expansion rate is low. The shadow mask electrode is supported by a shadow mask electrode supporting body made of metal whose thermal expansion rate is approximately the same as that of the shadow mask electrode. The shadow mask electrode supporting body is supported by a frame body made of metal whose thermal expansion rate is different from that of the shadow mask electrode.
