Manufacturing method for plasma display panel |
摘要 |
The present invention aims to provide a manufacturing method for a PDP which allows even high-definition and ultra-high-definition PDPs to demonstrate an excellent image display capability at improved luminous efficiency, by suppressing variation of a discharge gas composition, and by eliminating an impurity gas in a discharge space effectively. To achieve the aim, deterioration of an absorbent material 39 composed of copper ion-exchanged ZSM-5-type zeolite is prevented, by performing both sealing and evacuation steps for the front substrate 2 and back substrate 9 in a non-oxidizing gas atmosphere. This maintains properties of the absorbent material 39 for absorbing the impurity gas without degradation, even if the absorbent material 39 absorbs a Xe gas in a discharge gas introducing step. |
