  • Patent number: 7053552
    Abstract: It is aimed to provide a technique for easily suppressing swellings produced in end parts of partitions, thereby achieving a PDP capable of displaying a high-quality image. A PDP therefore has a plurality of partitions that include: (a) a plurality of main parts; and (b) a plurality of sub parts that each extend from an end part of one of the plurality of main parts parallel to a direction perpendicular to a direction in which the main parts extend. This allows each partition to have an end that is wider than a center part of the partition. In the process of forming PDP partitions, end parts of the partitions are partially heated, after they are baked, to a temperature higher than a softening point of a partition material. As a specific partial heating method, a method with which a laser beam is projected onto an end part is suitable.

  • Patent number: 7040947
    Abstract: A method of manufacturing at least two layer electrodes that can be utilized, for example, as bus and data electrodes in a plasma display device, includes depositing each layer in a coating step and subsequently exposing the layers at the same time for development. The layers are subsequently baked at the same time. One layer can be thinner than the other layer during a time period between the developing step and the baking step.

  • Patent number: 7034458
    Abstract: A manufacturing method for a metal electrode used for a bus electrode, a data electrode, and the like which make up a display panel including a PDP (Plasma Display Panel) by which, when these electrodes are patterned according to a photolithographic method, the edge curl phenomenon can be substantially controlled to the extent that the phenomenon is negligible. The manufacturing method of the invention therefore includes a dry step for drying the layers making up the metal electrode so that flows (F1, F2, and F3) of the solvent occur from a region having a high absorbency of the solvent to a region having a lower absorbency of the solvent.

  • Patent number: 7002297
    Abstract: To provide a technique for relatively easily preventing yellowing of a PDP that uses silver electrodes, and a PDP utilizing the technique that is capable of displaying images with high luminance and high quality. To form the electrodes, an alloy composed of Ag as a main constituent and a transition metal (at least one selected from Cu, Cr, Co, Ni, Mn, and Fe) is used, or an oxide of such a transition metal is added. Alternatively, an alloy composed of Ag as a main constituent and a metal (at least one selected from Ru, Rh, Ir, Os, and Re) is used, or an oxide of such a metal is added. Alternatively, Ag particles whose surfaces are each coated with a metal (Pd, Cu, Cr, Ni, Ir, or Ru) or a metal oxide (SiO2, Al2O3, NiO, ZrO2, Fe2O3, ZnO, In2O3, CuO, TiO2, or Pr6O11) are used.

  • Publication number: 20050181697
    Abstract: An object of the present invention is to provide a method for manufacturing electrodes that can effectively suppress edge-curl when metal electrodes such as bus electrodes and data electrodes are patterned mainly by a photolithography method. In order to achieve the above object, in the manufacturing method in the present invention, an amount of undercut generated by difference in a degree of dissolution caused by developing solution is controlled, and baking is performed at a temperature such that glass in a protrusion formed at side edges becomes soft so as to touch a substrate by gravity. With such method for manufacturing, it becomes possible to make the side edges rounded whose curvature changes continuously.
