Abstract
In a plasma display panel, a partition wall defining a discharge space is formed of a thermal-sprayed film formed by thermal spraying of a partition wall material. A process for forming such a partition wall 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 a 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.
