Patent 7557507 was granted and assigned to AU Optronics on July, 2009 by the United States Patent and Trademark Office.
An electrode on a substrate of a plasma display panel has a relatively narrow bus line conductor at an intersection with a pad, and a line width of the pad being wider than a line width of the bus line conductor and substantially narrower than a line width of a wider section of the pad, which avoids a break in the electrode when the electrode is fired at an elevated temperature.
