摘要： A plasma display panel demonstrating excellent image display performance by suppressing generation of initialization bright points through modification of the phosphor layer, and by eliminating variation in discharge characteristics between the discharge cells of each color. In addition to solving these problems, the luminance of the plasma display panel is also enhanced by using the ultraviolet rays emitted in the discharge space in order to promote the production of visible light on the front panel side. Specifically, the phosphor layer (14) is composed of a phosphor component and of MgO powder (16) disposed principally inside the phosphor layer and exposed towards the surface (140) facing the discharge space in order to impart secondary electron emission characteristics. The MgO powder (16) is composed of MgO particles (16a-16d) having a crystal structure with two specific crystal faces consisting of the (100) crystal face and the (111) crystal face, or three specific crystal faces consisting of the (100) crystal face, the (110) crystal face, and the (111) crystal face.

The PDP has a protective layer that is composed of an MgO film layer and an MgO particle layer made of MgO particles. The MgO particles are formed by burning an MgO precursor and satisfy that a/b≧1.2, where a denotes a spectrum integral value in a wavelength region of a CL spectrum from 650 nm to 900 nm, exclusive of 900 nm, and b denotes a spectrum integral value of a wavelength region of the CL spectrum from 300 nm to 550 nm, exclusive of 550 nm. The MgO particles have many high energy levels in the energy band and thus emission of initial electrons is caused more easily, which leads to suppress discharge delay and also to suppress temperature dependence of the discharge delay.

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.

摘要： “Discharge delay” and “dependence of discharge delay on temperatures” are solved by improving a protective layer, thus a PDP can be driven at a low voltage. Furthermore, the PDP can display excellent images by suppressing “dependence of discharge delay on space charges.” Liquid-phase magnesium alkoxide (Mg(OR)2) or acetylacetone magnesium ate whose purity is 99.95% or more is prepared, and is hydrolyzed by adding a small amount of acids to the solution. Thus, a gel of magnesium hydroxide that is a magnesium oxide precursor is formed. Burning the gel in atmosphere at 700° C. or more produces powder containing MgO particles 16a-16d having the NaCl crystal structure with (100) and (111) crystal faces or with (100), (110) and (111) crystal faces. By pasting the powder on a dielectric layer 7 or a surface layer 8, the MgO powder 16 is formed so as to serve as the protective layer.
