Plasma display panel and method of separating the same

A method of separating a plasma display panel into a front panel and a back panel, comprising:

• heating said plasma display panel for softening a bonding material used between said front panel and said back panel;
• and
• removing said bonding material by means of suction or absorption through a groove provided on at least one of said front panel and said back panel.

A method of separating a plasma display panel into a front plate and a back plate, comprising:

• heating or cooling said plasma display panel through a laminated graphite sheet provided on either an upper surface or a side surface of at least one of said two plates.

A method of separating a plasma display panel into a front panel and a back panel, comprising:

• immersing said plasma display panel in an etching solution capable of selectively dissolving lead oxide-contained glass bonding the front panel and the back panel;
• and
• preventing the etching solution from leaking onto an image display screen by a groove provided in an area between a bonding portion and the image display screen of at least one of the front panel and the back panel.
