Abstract
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 A and B for damping the vibrations of a flat grille are provided in upper and lower regions of the flat grille outside an effective screen region of a cathode-ray tube. The damper members A and B are supported under a given tension by support members and mounted on second frames A and B of a frame member, thereby keeping pressure contact with the surface of the flat grille Because the damper members A and B are not exposed to the effective screen region of the cathode-ray tube, the damper members A and B are out of sight from the front side of the screen, thus suppressing the vibrations of the flat grille without marring the appearance of the screen.
