PURPOSE: A plasma display panel is provided to prevent a plate from breaking by a heat and a shock by providing a mark showing a feature of a plate inside a plate. CONSTITUTION: A plasma display panel includes a mark showing a feature of a process starting day, a type of a machine, a degree, a size inside a plate. An electrode is formed at the inner surface of the plate, and the PDP displays a predetermined pattern by exciting a fluorescent material according to a driving of the electrode. The mark is formed by IGM(Intravolume Glass Marking) technology. A diameter of a laser beam using at the IGM technology is 10mm, and an energy per a unit area(mm¬2) is 1.3 micro joule. |
