摘要： A plasma display panel is composed of a first substrate and a second substrate facing each other via a discharge space and sealed together. A protective layer on the first substrate is composed principally of magnesium oxide, includes a substance or structure that creates a first energy level in an area of a forbidden band, the area being in a vicinity of a conduction band, and includes a substance or structure that creates a second energy level in another area in the forbidden band, the other area being in a vicinity of a valence band. During driving the second energy level is occupied by electrons, and few electrons exist in the first energy level, or electrons can easily occupy the first energy level due to a minus charge state, and MgO insultaive resistance is not lowered. This maintains wall charge retention and reduces discharge irregularities and firing voltage Vf.

摘要： A gas discharge display panel exhibits a favorable display performance by increasing a wall charge retaining property, controlling a discharge delay for optimal image display, and reducing the discharge starting voltage. A PDP can exhibit enhanced display quality by improving a secondary electron emission factor γ compared to conventional cases and lowering the discharge starting voltage to widen the driving margin. A manufacturing method for a gas discharge display panel can reduce the exhaustion time in the sealing exhaustion process, and driving circuit component costs are reduced. In a gas discharge display panel, a protective layer includes a first and a second protective film, the second protective film is formed on at a least part of a surface of the first protective film. The first protective film has a larger impurity content than the second protective film.

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.
