Patent ID: 6860780

Claim:
A method for producing a plasma display panel that has a front substrate and a back substrate disposed to face each other, the method comprising: a pre-baking phosphor layer forming step for forming a pre-baking phosphor layer containing a phosphor and an organic binder, on at least one of the surfaces of the front substrate and the back substrate that are to face each other; a sealing material applying step for applying a sealing material that softens with heat, to the peripheral region of at least one of the surfaces of the front and back substrates that are to face each other; a stacking step for, after the pre-baking phosphor layer forming step and the sealing material applying step, disposing the front and back substrates to face each other in a stack; and a baking step for heating the front and back substrates to burn out the organic binder while supplying a dry gas containing oxygen to an internal space that is formed between the front and back substrates, wherein the organic binder is burned out and the sealing material is softened to enable bonding of the front and back substrates in a simultaneous operation of raising and lowering temperature.
