Abstract:
A method for producing a plasma display panel, comprising a partition wall formation process of forming a partition wall defining a discharge space of a thermal-sprayed film formed by thermal spraying of a partition wall material,wherein the partition wall formation process includes the steps of: forming a photosensitive coating layer on a substrate; forming an opening having a prescribed pattern in the photosensitive coating layer; depositing the partition wall material to a prescribed height at least inside the opening by the thermal spraying technique, thereby forming the thermal-sprayed film; removing a portion of the thermal-sprayed film bulging out from a surface of the photosensitive coating layer by polishing; and removing the photosensitive coating layer to obtain the partition wall having a prescribed shape, wherein the partition wall has a multiple-layer structure including at least a first layer formed by depositing a first partition wall material at a plasma energy quantity A and a second layer formed by depositing a second partition wall material on the first layer to a prescribed height at a plasma energy quantity smaller than the plasma energy quantity A, where A is the plasma energy quantity at the time of thermal spraying in an area where at least thermal spray particles tightly adhere to the substrate.
