  • Patent number: 8318392
    Abstract: An alignment method is disclosed, in which a distance between a substrate and a photomask is set at a predetermined exposure gap. The photomask is rectangular, and includes a first side, and a second side opposite to the first side. A distance between a midpoint of the first side and the substrate is matched with the exposure gap. The photomask is rotated about, as an axis, a line that connects the midpoint of the first side and a midpoint of the second side to each other, whereby distances between both ends of the first side and the substrate are individually matched with the exposure gap. The photomask is rotated about the first side taken as an axis, whereby a distance between the midpoint of the second side and the substrate is matched with the exposure gap.

  • Publication number: 20110221728
    Abstract: Having a low-cost transparent electrode, the plasma display panel suppresses variations in discharge characteristics between discharge cells and provides high quality image. To attain above, a scan bus electrode is formed so as to constitute an outer periphery in the lengthwise direction of a scan electrode and have a clearance inside, similarly, a sustain bus electrode is formed so as to constitute an outer periphery in the lengthwise direction of a sustain electrode and have a clearance inside. Besides, a scan transparent electrode is formed in the clearance of the scan bus electrode with use of a dispersion liquid containing particles of metal or particles of metal oxide, similarly, a sustain transparent electrode is formed in the clearance of the sustain bus electrode with use of a dispersion liquid containing particles of metal or particles of metal oxide.

  • Publication number: 20110102399
    Abstract: The present invention provides a plasma display panel having a low-cost transparent electrode, without decrease in yield. To achieve above, the panel has a first bus electrode, a second bus electrode, a first transparent electrode, and a second transparent electrode on the front substrate. The first transparent electrode covers at least a part of the first bus electrode, and similarly, the second transparent electrode covers at least a part of the second bus electrode.

  • Publication number: 20110018927
    Abstract: The present invention provides a method for manufacturing a panel. According to the method, employing an ink containing particles of metal or particles of metal oxide allows transparent electrodes to be formed with high dimensional accuracy and little loss of productivity. Specifically, the transparent electrodes are formed in a manner that an ink containing particles of metal or particles of metal oxide is printed by inkjet printing as a plurality of ink dots with different diameters onto the front substrate.

  • Publication number: 20100207922
    Abstract: Having a low-cost transparent electrode, the plasma display panel suppresses variations in discharge characteristics between discharge cells and provides high quality image. To attain above, a scan electrode has a scan transparent electrode formed by applying a dispersion liquid containing particles of metal or metal oxide onto a front substrate, and a scan bus electrode on the front substrate. A sustain electrode has a sustain transparent electrode formed by applying a dispersion liquid containing particles of metal or particles of metal oxide onto the front substrate, and a sustain bus electrode on the front substrate. Besides, a discharge gap is formed by a scan bus electrode and a sustain bus electrode. An outer periphery section on a discharge-gap side of a scan transparent electrode overlaps with a scan bus electrode, and an outer periphery section on a discharge-gap side of a sustain transparent electrode overlaps with a sustain bus electrode.
