Abstract: In a color selecting mechanism (1) for a color cathode ray tube, in which a color selecting electrode, having grid elements (8) and slit shaped apertures (9) formed there-between, is seam-welded on a frame (2,3,4), the ratio of the distance (b) from the ends of the apertures (9) to seam-weld (17) to the length (a)of the apertures (9) is set equal to or less than 2.5 percent. Such a construction damps vibration quickly and allows damper wires (12, fig 4) to be positioned outside the effective picture area of the screen.

Abstract: It is possible to improve a vibration-proof band shaped grid element in a color selecting mechanism. In a color selecting mechanism 1 for a color cathode ray tube, in which a color selecting electrode thin plate (10) having a number of band shaped grid elements (8) and a slit shaped electron beam penetrating aperture (9) formed between respective neighboring grid elements (8), is seam-welded on a frame (6), the ratio of a length a of the above mentioned slit shaped electron beam aperture (9) to a distance (b) from an end portion of the above mentioned electron beam penetrating aperture (9) to a seam-welded orbit (17) or b/ax100 is set equal to or less than 2.5 percent.

Abstract: A colour picture tube is provided with a glass bulb (1) in which the external surface (10A) of the effective display area of the face plate (10) is formed substantially flat and a colour selection mask (20), having the curvature thereof projected toward the face plate, provided opposed to the internal surface (10B) of the face plate within the glass bulb. Therefore, the external surface is flat, the mechanical shock resistance characteristic is high, a tension can surely be applied to the colour selection mask and moreover vibration of the colour selection mask can be prevented even if external vibration is applied thereto.
