摘要

A method is provided for manufacturing a support frame of a rectangular display panel within a short working time. The method includes a process of taking out L-shaped component members each having convex portions and concave portions arranged alternately at an end portion in a manner that each of the convex portions and concave portions is bilaterally symmetrical, while a shear droop and a burr are formed on an end portion and process of fitting and coupling end portions of L-shaped component members by placing the convex portions and the concave portions in such a manner that the shear droop of each of the convex portions faces the burr of each of the concave portions and the burr of each of the convex portions faces the shear droop of each of the concave portions and that that the convex portions and the concave portions are pushed towards each other and by pressing the convex portions and the concave portions using a pair of metal molds.
