Abstract
This invention intends to provide an aperture grill supporting frame whereby forces exerted by damper wires on individual thin tapes constituting an aperture grill are uniform. This object is achieved by the following: the surfaces for welding of upper and lower frames of an aperture grill supporting frame are so processed from the beginning as to have sizes compensatory for deformations occurring as a result of pressurization and thus they will form a part of a columnar wall surface with a radius of R when they subject to deformations in the presence of a pressure. Thus, the surfaces for welding at both ends, for example, take a slightly bulged form as compared with a sector of a radius of R before they are subject to welding.
