ABSTRACT:
A beam guide assembly for a flat panel display device includes a plurality of meshes arranged in a spaced parallel relationship. Insulative supports permanently retain the meshes in a desired spaced relationship. Shields are arranged between the various meshes to shield the beam guide assembly from external electric fields and to prevent the insulative supports from being charged by stray electrons and deleteriously effecting the paths of the electron beams.
