A color picture tube provided with a plurality of shadow masks, each of which is formed of a main part having a curved surface with a large number of apertures and a skirt section supporting the peripheral portion of said main part, and the curved surfaces of said plural shadow masks are spaced from each other at a prescribed distance. The parts extending substantially perpendicularly to the curved surfaces of the skirt sections of at least two of the plural shadow masks is comprised of alternately arranged support portions and intervening cutouts. The support portions of the skirt section of one shadow mask face the corresponding alternate cutouts of the skirt section of the other shadow mask and the cutouts of the skirt section of said one shadow mask face the support portions of the skirt section of the other shadow mask so as not to overlap each other.
