US Patent 7368871 Plasma display apparatus with improved substrates

A plasma display apparatus includes a plasma display panel having a first substrate, a second substrate facing the first substrate and sealed thereto, and a plasma discharge structure disposed between the first and second substrates. A chassis base is positioned close to the plasma display panel at one surface side and in parallel with the panel. A driving circuit is mounted on the opposite surface side of the chassis base and electrically connected to the plasma display panel to drive the panel. The first and second substrates of the plasma display panel have chamfered portions formed along the edges of the first and second substrate surfaces that face away from each other.
