description 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 (1) with good properties of, for instance, color purity, it is of eminent importance that the positional stability of the color selection electrode (12) is excellent. Especially wide-screen tubes seem to be more sensitive to 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 increasing the stiffness of the corner sections (16) of the color selection electrode (12). This can be realized by introducing an additional support plate (41) in the corner section (16). Also the optimization of the position of the supporting element (17) with respect to this corner section (16) yields an improvement.
