Abstract
A method of manufacturing a shadow mask assembly, in which a shadow mask is fastened to a support frame in a tensioned state, includes applying a preliminary tension force with a magnitude of 9.8 to 490 N to the four corners of the shadow mask outwardly aslant with respect to sides of the shadow mask. A main tension force is then applied to each of at least a pair of mutually opposite sides of the shadow mask outwardly perpendicularly to the sides. Thereafter, the shadow mask to which the main tension forces have been applied is fastened to the frame side of the support frame.
