Abstract

A method for the manufacture of a cathode ray tube for presenting color images and comprising means for generating a in an empty housing. a certain number of electron beams, a display screen comprising a large number of regions that glow in different colors, and color selection means comprising a large number of apertures associating each electron beam with luminescent regions of one color, which color selection means comprise electrodes to form an electron lens in each opening, characterized in that the color selection means are manufactured based on a few metal plates that are fixed to each other with the interposition of insulation material so that the plates do not come into contact with each other, at least one of the plates being provided, before the plates are fixed together, with an embossed design that is composed of a number of substantially parallel ribs between which they are a certain number of strip-shaped regions are present in which the plate or plates has (are) a thickness much smaller than next to the rib area, the material being removed from said strip-shaped regions after jointly fixing the plates.
