摘要： A protective layer has, on its back side, an electron emissive layer formed of magnesium oxide crystals. Based on a front view of discharge cells C, there are defined intersection regions (first regions) where display electrode pairs (each including a sustain electrode X and a scan electrode Y) and address electrodes Z intersect and a remaining region (a second region) E1 excluding the intersection regions. The surface density of the magnesium oxide crystals forming the electron emissive layer over the intersection regions (the first regions) is equal to or lower than half the surface density of the magnesium oxide crystals forming the electron emissive layer over the remaining region (the second region) E1 excluding the intersection regions.

摘要： In a light emitting display device using electron emitter elements, it is possible to prevent lowering of image quality caused by spread of electron beams. MIM (Metal Insulator Metal) is used as the electron emitter elements and each of the electron emitter elements is surrounded by a conductive barrier (scanning wire). The electron emitter elements and the barriers are covered by upper electrodes so that the barriers and the surfaces of the electron emitter elements have the same electrical potential. The electron emitter elements and the barriers are formed on a cathode substrate. Color phosphors of R (red), G (green), and B (blue) are formed on an anode substrate at the side opposing to the cathode substrate. The color phosphors are excited by electron beams emitted from the electron emitter elements.
