ABSTRACT:
An electron beam guide assembly for a flat panel display device includes two guide meshes. One mesh is substantially flat and the other is shaped. The shaped mesh has a substantially flat surface and includes longitudinal sides which extend angularly away from the flat surface. The sides are further shaped to include flanges which lie in a plane substantially parallel to and displaced from the flat surface. The flanges are joined to the flat mesh to form an assembly having continuously shielded longitudinal sides.
