Abstract
The invention relates to a color display tube having a color selection electrode which is suspended in the tube by engagement of apertured elements connected to flat resilient elements extending from the corners of the electrode, with the spherical heads of pins extending from the corners of the display window. According to the invention, a rigid construction is obtained by providing apertures shaped so that each spherical part has at least three points of engagement with its respective apertured element, and at least one point of engagement is outside the plane of the flat resilient element.
