An aperture grille which can suppress vibrations of a flat grille without marring the appearance of a screen by not arranging damper lines inside an effective screen region of a cathode-ray tube. A pair of damper members 130A and 130B for damping the vibrations of a flat grille 110 are provided in upper and lower regions of the flat grille 110 outside an effective screen region of a cathode-ray tube. The damper members 130A and 130B are supported under a given tension by support members 132 and 134 mounted on second frames 124A and 124B of a frame member, thereby keeping pressure contact with the surface of the flat grille 110. Because the damper members 130A and 130B are not exposed to the effective screen region of the cathode-ray tube, the damper members 130A and 130B are out of sight from the front side of the screen, thus suppressing the vibrations of the flat grille 110 without marring the appearance of the screen.
In an aperture grille for a cathode-ray tube, having a flat grille as an electrode sheet formed with vertical stripes of slits and line electrodes, and a frame member to which said flat grille is connected under a given tension, the frame member having a pair of first frames connected to opposite ends of said flat grille corresponding to opposite ends of said slits;
