Abstract
A PDP and a manufacturing method for the PDP are provided, the PDP being capable of suppressing discharge delay due to improved discharge properties of a protective layer, and exhibiting superior image display performance despite having a high-definition cell structure. A magnesium oxide powder layer () is formed by distributing magnesium oxide particles () flatly on a surface layer (). Each of the magnesium oxide particles () includes halogen atoms at and in a vicinity of the surface thereof. The magnesium oxide particles () are manufactured such that the halogen atoms exist particularly at the surface of each of magnesium oxide particles () through to a depth of 4 nm or less toward the core of each of the magnesium oxide particles ().
