Abstract
A color selecting electrode assembly for color cathode ray tubes which includes an apertured grill composed of fine-strand grids, a frame over which the aperture grill is stretched and which provides a tensioning force to the apertured grill, and a supporting structure body which is mounted at one end to said frame and engages the other end with the panel side wall of a color cathode ray tube so as to support said frame, wherein the wall thickness of said apertured grill is not greater than 0.032 mm. To assure the characteristic frequency of the aperture grill, it becomes unnecessary to manufacture individually frames having rigidities corresponding to respective slit pitches of the apertured grill. The frame can be a general purpose one (i.e., one used in common with others), thereby allowing the manufacture to be simplified. Further, the suppoting member can be also used in common with others, thereby allowing the design to be simplified.
