Abstract
A PDP can be driven at low voltage while having a charge retention property in a protection layer, and has favorable image display properties. Additionally, the PDP prevents the occurrence of discharge delay and realizes high-quality image display by performing favorable high-speed driving in a high definition PDP. To achieve this, a surface layer () is formed to a film thickness of 1 μm in an oxygen atmosphere having an oxygen partial pressure of 0.025 Pa or more, the surface layer () is provided on a face of a dielectric layer () on a discharge space side. Furthermore, MgO particles () are dispersed on a surface of the surface layer (). The surface layer () has the effects of protecting the dielectric layer () from ion bombardment during discharge, reducing the firing voltage, and preventing excessive electron loss. Also, the MgO particles () have a high initial electron emission property.
