ABSTRACT:
In a flat panel display device including spaced parallel guide meshes between which electron beams propagate, the guide meshes are formed to include projections extending into the electron beam propagation space. The projections restrict the electron propagation space in a direction perpendicular to the planes of the guide meshes and thus capture electrons near the extremities of the space.
