A method for manufacturing a plasma display panel in which an electrical discharge gas is introduced into a space between a first substrate and a second substrate which are sealed together, the method including: a first deaeration step of releasing impurity gases from a protective film by heating the first substrate, on which the protective film is formed for withstanding plasma electrical discharge, to 280&#xb0; C. or more in a vacuum or in a controlled atmosphere; and a sealing step of sealing the front substrate, in which the impurity gases have been released from the protective film, and a rear substrate which are placed in contact with each other.

Method and apparatus for manufacturing plasma display panel

A method for manufacturing a sealed panel having a first substrate and a second substrate, including: a melting step of melting a sealing material which does not contain a binder for making the sealing material into paste form; a coating step of applying the melted sealing material onto a surface of the second substrate; and a sealing step of laminating the first substrate and the second substrate via the sealing material applied onto the surface of the second substrate.

Method and apparatus for manufacturing sealed panel and method and apparatus for manufacturing plasma display panel

A plasma display panelof the present invention has a protective filmover a sustaining electrodeand a scanning electrodewith the main components of the protective film being CaO and SrO, and the concentration of the CaO in the protective filmis 20 mol % or more and 90 mol % or less. This protective filmhas a smaller work function than a conventional MgO film so light can be emitted at a lower discharge voltage than in the past. If the discharge voltage is lower, the protective filmwill be sputtered more slowly so that the service life of the plasma display panelwill be longer. Also, since the plasma-gas contains xenon gas, the plasma display panel of the present invention has higher brightness.
