ABSTRACT:
A color selecting electrode mounting frame of a CRT which eliminates the waste of materials, is easy and inexpensive to process and assemble. The color selecting electrode mounting frame for a CRT comprises a pair of long members of an L-sectional shape having curved surfaces formed at their top edge portions to which two opposing sides of a color selecting electrode are attached and a pair of short members having end portions joined to the two ends of these long members. The long members are obtained by blanking a plate of a fixed width into an arc shape of a predetermined curvature, then forming this into an L-sectional shape and a curvature matching the panel glass surface of the CRT. The two end portions of the short members are processed to match the curvature of the two end portions of the long members. The end portions of the short members are processed by a twisting, crushing, or shaving process.
