ABSTRACT:
A shadow mask support assembly for a color cathode-ray tube prevents partial thermal deformation generated by welding a shadow mask and a mask frame. Also, the shadow mask support assembly for a color cathode-ray tube includes a mask frame suspended and supported in the inner face of the panel, a shadow mask inserted in the inner circumference of the mask frame, and an elastic band for supporting the inner circumference of the mask frame body which presses a skirt portion of the shadow mask from its outer circumference to prevent welding the mask frame and the shadow mask.
