Abstract
A cathode ray tube with a shadow mask, the shadow mask structure being suspended and fixed behind the panel of the cathode ray tube. Plate springs for connecting the shadow mask structure and the panel are placed to apply pulling forces at either the sides or the corners of the shadow mask frame, so as to firmly hold the shadow mask to the skirt without deforming the shadow mask.
