  • Patent number: 7649314
    Abstract: A plasma display panel reduces a resonance space between a frit and dummy partition walls so as to suppress noise and smoothly supply and exhaust a discharge gas. The plasma display panel includes a front substrate and a rear substrate that face each other, address electrodes and display electrodes that are spaced apart from each other and each extend along directions intersecting each other between the front substrate and the rear substrate, and partition walls that form a display region while partitioning a plurality of discharge cells and form a non-display region along a periphery of the display region between the front substrate and the rear substrate. The non-display region includes a first dummy area in which dummy cells are partitioned by dummy partition walls extending from partition walls disposed in the display region, and a second dummy area in which dummy cells are partitioned by dummy partition walls spaced apart from the first dummy area.

  • Patent number: 6872115
    Abstract: One object of the present invention is to provide a blade for forming ribs that is able to improve wear resistance; in order to achieve the object, the present invention provide a blade for forming ribs that forms ribs either on the surface of a substrate or via an undercoating layer on the surface of a substrate by moving a blade body in a fixed direction relative to a paste film in the state in which comb teeth formed on at least a portion of the periphery of said blade body are penetrated into said paste film formed on the surface of said substrate to plasticly deform said paste film; wherein, the surface of said comb teeth formed on said blade body that makes contact with said paste film is coated with a compound layer in which hard particles are dispersed in a metal.

  • Patent number: 6650051
    Abstract: In a plasma display panel, a scanning electrode and a common electrode are alternately formed in strips and parallel to one another on a lower surface of a front substrate. A bus electrode is formed on lower surfaces of the respective scanning and common electrodes to have a narrower width than that of each of the scanning and common electrodes. A black matrix layer is formed of the same insulative material to be parallel to the electrodes at a boundary area between neighboring discharge cells, in which each cell is constituted by a discharge space including a pair of the scanning electrode and the common electrode, and between the scanning and common electrodes and the bus electrode, on a lower surface of the front substrate.
