摘要： 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 (8) 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 (8) is provided on a face of a dielectric layer (7) on a discharge space side. Furthermore, MgO particles (16) are dispersed on a surface of the surface layer (8). The surface layer (8) has the effects of protecting the dielectric layer (7) from ion bombardment during discharge, reducing the firing voltage, and preventing excessive electron loss. Also, the MgO particles (16) have a high initial electron emission property.

A protective layer of the PDP is composed of an MgO film layer and an MgO particle layer that is made of MgO particles. The MgO particles are formed by burning an MgO precursor and satisfy that a/b≧1, where a denotes a spectrum integral value in a wavelength region of a CL spectrum from 200 nm to 300 nm, exclusive of 300 nm, and b denotes a spectrum integral value in a wavelength region of the CL spectrum from 300 nm to 550 nm, exclusive of 550 nm. With provision of the MgO particle layer, the discharge characteristics of the protective layer improve (shorter discharge delay and less temperature dependence of the discharge delay). Consequently, the PDP is ensured to exhibit excellent display performance.
