Abstract: A shadow-mask cathode ray tube for the visualization of colors, such as in television, where the peripheral edge of the mask is rigid with the frame fixed on the tube plate and is in contact with said frame only in areas spaced from each other. The frame is formed with bosses providing its contact in reduced cross-section areas spaced from each other with the edge of the mask.
