ABSTRACT:
A flat display device includes cathodes, a screen plate having a fluorescent screen, a plate-like electrode for controlling electron beams from the cathodes to the fluorescent screen, and a frame body for supporting the plate-like electrode. The frame body securely fixes both ends of the plate-like electrode at two opposite sides thereof, and has an elastic body for supporting the plate-like electrode in a stretched state by a spring force of the elastic body. The flat display device is made by the steps of pressing a pair of leaf springs provided respectively at two confronting sides of a frame body to thereby bend the frame body in such directions that the confronting sides become close to each other, securely fixing both ends of a plate-like electrode to the pair of bent leaf springs, and releasing the pressing of the leaf springs to thereby restore the leaf springs.
