Embodiment approach

[0055] figure 1 It is a perspective view showing the structure of PDP1 which concerns on embodiment of this invention. The basic structure of the PDP1 is the same as that of a common AC surface discharge type PDP. Such as figure 1 As shown, in PDP1, a first substrate (hereinafter referred to as front panel 2) composed of front glass substrate 3 and the like and a second substrate (hereinafter referred to as rear panel 10) composed of rear glass substrate 11 and the like are opposed to each other. The outer peripheral part is hermetically sealed by a seal made of glass frit or the like. Discharge gases such as xenon (Xe) and neon (Ne) are enclosed at a pressure of 400 Torr (53300 Pa) to 600 Torr (80000 Pa) in the discharge space 16 inside the sealed PDP 1 .

[0056] On front glass substrate 3 of front panel 2 , a pair of strip-shaped display electrodes 6 and black stripes (light shielding layers) 7 composed of scan electrodes 4 and sustain electrodes 5 are arranged in multip...

Abstract

Provided is a low-power-consumption plasma display panel with high-definition and high-luminance display performance. In a front plate, display electrodes, a dielectric layer, and a protective layer are formed. The display electrodes are formed on a front glass substrate. The dielectric layer is formed so as to cover the display electrodes. The protective layer is formed on the dielectric layer. In a back plate, address electrodes, and ribs that partition a discharge space are formed in the direction crossing the display electrodes. The front plate and the back plate are disposed facing each other so as to form the discharge space therebetween, and a discharge gas is filled therebetween. The protective layer is formed by a metal oxide produced from magnesium oxide and calcium oxide. In the X-ray diffraction analysis in the protective layer plane, the metal oxide has a peak between the diffraction angle at which the peak of magnesium oxide occurs and the diffraction angle at which the peak of calcium oxide in the same orientation as the peak of magnesium oxide occurs.

Description

technical field [0001] The present invention relates to plasma display screens used in display devices and the like. Background technique [0002] Since the plasma display panel (hereinafter referred to as "PDP") can realize high-definition and large-screen size, 100-inch-class TVs and the like have been commercialized. In recent years, PDP is more suitable for high-definition televisions with more than twice the number of scanning lines than the existing NTSC method. In addition, there is a demand for PDPs capable of solving energy problems by reducing power consumption, and PDPs that do not contain lead components are required in consideration of environmental problems. [0003] A PDP is basically composed of a front panel and a rear panel. The front panel is composed of the following components: a glass substrate of sodium borosilicate glass produced by a float process; a display electrode composed of strip-shaped transparent electrodes and bus electrodes formed on one ...
