Claim:
A method for manufacturing a support frame of a rectangular display panel having an approximately rectangular-shaped configuration and being used to support a portion surrounding said rectangular display panel, said method comprising: a first process of taking out a plurality of component members each having convex portions and concave portions arranged alternately at an end portion of each of said plurality of said component members in a manner that each of said convex portions and said concave portions is bilaterally symmetrical and making up said support frame by being assembled in combination, while a shear droop and a burr are formed at each end portion of each of said plurality of said component members, from a plate material; and a second process of fitting and coupling end portions of said plurality of said component members by placing said convex portions making up an end portion of each of said plurality of said component members to be assembled in combination and said concave portions making up said end portion of each of said plurality of said component members to be assembled in combination in such a manner that said shear droop of each of said convex portions faces said burr of each of said concave portions and said burr of each of said convex portions faces said shear droop of each of said concave portions and, while a force is applied so that said convex portions and said concave portions are pushed towards each other, by pressing both said convex portions and said concave portions in upward and downward directions using a pair of metal molds on which projected portions are formed on a surface of one or both of said metal molds in a position being apart by a specified distance from said each end portion of two of said component members to be assembled out of said plurality of said component members or from said end portion of one of said plurality of component members.
