Embodiment approach

[0034] figure 1 It is a perspective view showing the structure of PDP1 in the embodiment of the present invention. The basic structure of the PDP 1 is the same as that of a normal AC surface discharge type PDP. Such as figure 1 As shown, for PDP1, a first substrate (hereinafter referred to as front panel 2) composed of front glass substrate 3 and the like is opposed to a second substrate (hereinafter referred to as rear panel 10) composed of rear glass substrate 11 and the like. Arranged, the outer peripheral part is hermetically sealed by a seal made of glass frit or the like. Discharge gases such as neon (Ne) and xenon (Xe) are sealed in discharge space 16 inside the sealed PDP 1 at a pressure of 400 Torr to 600 Torr (53300 Pa to 80000 Pa).

[0035] On the front glass substrate 3 of the front panel 2, a pair of strip-shaped display electrodes 6 composed of scan electrodes 4 and sustain electrodes 5 and black stripes (light-shielding layers) 7 are arranged in parallel to e...

Abstract

Disclosed is a plasma display panel that can realize high-definition and high-brightness display properties and, at the same time, has low power consumption. The plasma display panel comprises a front plate comprising display electrodes, a dielectric layer, and a protective layer. The display electrode is provided on a front glass substrate. The dielectric layer is provided so as to cover the display electrode. The protective layer is provided on the dielectric layer. A back plate comprises address electrodes in a direction that crosses the display electrodes, and partition walls that partition a discharge space. The front plate and the back plate are disposed opposite to each other so as to form the discharge space, and a discharge gas is filled into the discharge space. The protective layer has a substrate film provided on the dielectric layer. Agglomerated magnesium oxide crystal grains are deposited on the substrate film. Further, the substrate film contains a metal oxide comprising at least two oxides selected from magnesium oxide, calcium oxide, strontium oxide, and barium oxide. Regarding the metal oxide, the X-ray diffraction analysis of the surface of the substrate film shows a peak between a minimum diffraction angle and a maximum diffraction angle derived from a simple substance of the oxide constituting the metal oxide in a specific plane direction.

Description

technical field [0001] The present invention relates to a plasma display panel used for display devices and the like. Background technique [0002] Plasma display panels (hereinafter referred to as "PDPs") are commercialized as 100-inch-class televisions and the like because they can achieve high definition and large screen sizes. In recent years, the application of PDP to high-definition televisions, which have more than twice the number of scanning lines compared with the conventional NTSC system, is progressing. In addition, there is an increasing demand for structures that further reduce power consumption in response to energy issues, and PDPs that do not contain lead in consideration of environmental issues. [0003] A PDP basically consists of a front panel and a rear panel. The front panel is composed of the following parts: a glass substrate of borosilicate nano-silicate glass manufactured by the floating method, a display electrode composed of a stripe-shaped tran...
