Abstract
A color shadow mask assembly includes a shadow mask spaced apart from an inner surface of a face panel by a predetermined gap and having a curved surface, and a rectangular frame for supporting and fixing the shadow mask. The shadow mask and the frame are integrally formed by welding to fix a side wall of the frame to a skirt of the face panel. The skirt alternately overlaps inner and outer surfaces of the side wall of the frame at opposite surfaces between the skirt of the shadow mask and the side wall of the frame.
