Abstract
A color selecting structure for a TRINITRON cathode-ray tube, in which color phosphor stripes are provided and a single electron gun emits three beams, capable of minimizing vertical fringes that deteriorate the quality of a picture displayed on the screen and of attenuating the vibration of a FAG (framing aperture grille plate), includes a thin plate having a plurality of tape-shaped grid (2a) elements and apertures (2a), and fine wires (3) extended across the surface of the aperture grille plate so as to apply a pressure in the range of 6.73.times.10.sup.-6 lbf., 2.24.times.10.sup.-5 lbf. to each grid element (2a).
