Plasma display panel, fabrication apparatus for the same, and fabrication process thereof

In an apparatus including a first to a fourth chamber which are built in one body isolated from the atmosphere wherein processes of passivation layer formation, exhaust, discharge gas injection, and combination are carried out in the apparatus, a process for fabricating a plasma display panel comprising:

• a passivation layer formation step of forming a MgO passivation layer on a first substrate in the first chamber;
• a cleaning step of transferring the first substrate having the MgO passivation layer and a second substrate to the second chamber without being exposed to the atmosphere and carrying out vacuum exhaust or cleaning in the second chamber;
• a sealing material coating step of transferring the cleaned first and second substrates to the third chamber and coating the first substrate with a sealing material;
• and a combination step of transferring the sealing material coated first substrate and the second substrate to the fourth chamber, aligning the first and second substrates with each other while discharge gas is injected in the fourth chamber, and combining/attaching the first and second substrates with/to each other.
