Color display tube with improved suspension of the color selection electrode

A color display tube (1) is disclosed with an improved suspension of the color selection electrode (12). In order to have a color display tube with good properties of, for instance, color purity, it is of eminent importance that the color selection electrode (12) has and excellent positional stability. Especially wide screen tubes seem to be more sensitive to external shocks by which the color selection electrode (12) may shift and cause discolorations. The positional stability of the color selection electrode (12) can be improved by decreasing the friction between the color selection electrode (12) and the supporting elements (17) in the display window (3) of the color display tube (1). This is achieved by applying a supporting element (17) with a free end portion (22) having a small diameter and by applying a low force between the suspension means (20) and the supporting elements (17). As a consequence of the lightweight construction of the color selection electrode (12), this force can be lowered to about 4 newtons.
