Abstract: PROBLEM TO BE SOLVED: To remove a controversial point of an electronic arc without impairing brightness of a screen by forming an electrode strip (ST) wire of a resistance ST wire to receive a signal from a single phosphor ST wire and bias ST wires having a resistance value lower than it. SOLUTION: An ST wire 17 of an anode electrode of a flat display screen contains a resistance ST wire 18 to support phosphor elements 7 and at least single parallel biassing ST wires 19. The ST wire 18 is desirably provided in the lengthwise direction by the two biassing ST wires 19. An anode is electrically continuous, and is formed on a transparent base board 6 by the parallel ST wire 18 made of a transparent material such as In or a tin oxide. The ST wire is provided by the two highly conductive strip wires 19 composed of Al, Cu or Au. In a color screen, the strip wires 19 are connected to an internal connecting part of the phosphor ST wires 7 having the same color by one of these end parts. The ST 19 has a resistance value lower than a resistance value of a material to constitute the ST wire 18.

Abstract: PROBLEM TO BE SOLVED: To provide a planar display screen, wherein space between electrodes is wide and inner surfaces of a substrate does not become dirty by supporting a first electrode with a thin substrate and a thick reinforcing plate, and by demarcating an interior space by a peripheral frame disposed between electrodes on the outside of the effective surface of each of the electrodes. SOLUTION: In a planar display screen, including a first and a second electrode separated from each other by an interior space 12, the first electrode is supported by a thin substrate 10 and a thick reinforcing plate 21, and the second electrode is supported by a thin substrate 6 and a thick reinforcing plate 20. The space 12 can be fixed by a simple peripheral rigid frame 22, by enhancing rigidity of a structure by using the plates 20, 21 fixed to an outer surface of a screen. Further, the space 12 between the electrodes of the screen can be widened by thickening the thickness of the frame 22, while deformation of the screen caused by a pressure difference between the interior and the exterior of the screen can be prevented by giving sufficient rigidity to the screen by the plates 20, 21. Accordingly, a spacer can be dispensed with, while the pollution of the substrate 10 inner surfaces caused by adhesion, soldering, and the like can be prevented.
