Patent ID: 7400083

Claim:
A flat panel display device comprising: a back panel having a back substrate; a face panel having a face substrate; and a sealing frame which laminates peripheries of a display region formed at center portions of opposing faces of main surfaces of the back panel and the face panel and seals the inside of a lamination gap in a vacuum, wherein the flat panel display device further includes: a plurality of electron beam sources which are constituted of a plurality of cathode lines which are formed on a plane parallel to the main surface of the back substrate, have cathodes, extend in the first direction and are arranged in parallel in the second direction which intersects the first direction; first control electrodes which are arranged close to the cathode lines at least within the display region and control the takeout quantity of electrons from the cathodes; and second control electrodes which are positioned in the second direction with respect to the electron beam sources and operate to focus electron beams taken out from the electron beam sources in the direction toward the face panel, wherein the second control electrodes are constituted of a plurality of second control-electrode division electrodes which are divided in the first direction with respect to each electron beam source, and a first inter-control-electrode connection line which electrically connects the neighboring first control electrodes to each other in the second direction is provided between the divided second control-electrode division electrodes.
