PURPOSE: A plasma display panel is provided to obtain superior heat radiating property and shock absorption property by including a corrugated heat conductive plate. CONSTITUTION: An inner assembly(120) is welded to the rear side of a plasma display panel. A corrugated heat conductive plate(135) is arranged between the plasma display panel and the inner assembly. Adhesive layers are formed on both sides of the heat conductive plate. A support plate is arranged between the plasma display panel and the heat conductive plate or between the inner assembly and the heat conductive plate.
