  • Publication number: 20040113555
    Abstract: The present invention provides a plasma display panel (PDP) capable of simplifying the number of processes, reducing costs for materials, improving an exhausting function and preventing erroneous discharge and cross-talk phenomena between neighboring cells. The present invention provides a plasma display panel (PDP), including: a vertical barrier rib and a horizontal barrier rib, wherein the vertical barrier rib and the horizontal barrier rib form a hexagonal shape to encompass discharge cell region in all directions; a connection barrier rib connecting the vertical barrier rib to the horizontal barrier rib, wherein the connection barrier rib have a groove at a central portion thereof so that a length of the horizontal barrier rib is shorter than a distance between the vertical barrier ribs; and a gas-passing path formed above a top surface of the horizontal barrier rib of which height is lowered with respect to a surface of the vertical barrier rib.
