Problems solved by technology
Such yellowed glass absorbs light with a wavelength of 400nm. Therefore, in the PDP, the brightness of blue is reduced or the chromaticity is deteriorated. Therefore, it is particularly a problem on the front panel.
In addition, since the colloid of Ag or Cu is conductive, it becomes a cause of a decrease in the dielectric strength of the dielectric layer, and since it is precipitated as large colloidal particles that are much larger than ions, it reflects the light transmitted through the dielectric layer. light, which causes the brightness of the PDP to decrease

Embodiment Construction
[0077] Embodiments of the present invention will be described below. In addition, the following description is an example of this invention, and this invention is not limited to these.
[0078]
[0079] image 3 It is a partially cutaway perspective view showing the main configuration of the PDP of the present embodiment. figure 1 yes image 3 A cross-sectional view of the PDP is shown.
[0080] This PDP is of the AC surface discharge type, and has the same structure as the PDP of the conventional example except that the dielectric layer (first dielectric layer) is formed of the first glass described later.
[0081] This PDP is constructed by bonding front panel 1 and rear panel 8 together. The front panel 1 includes: a front glass substrate 2, a stripe-shaped display electrode 5 formed of a transparent conductive film 3 and a bus electrode 4 formed on the inner surface thereof (the surface on the discharge space 14 side), and a dielectric layer covering the display elec...

Abstract
This invention provides a plasma display panel comprising a display electrode (5) and an address electrode (10) which cross each other, at least one of the display electrode (5) and the address electrode (10) being covered with a first glass-containing first dielectric layer (6). The first glass is a Bi2O3-containing glass. The electrode covered with the first dielectric layer (6) comprises at least one of silver and copper. The first glass further comprises 0 to 4% by weight of MoO3 and 0 to 4% by weight of WO3. The total content of MoO3 and WO3 in the first glass is in the range of 0.1 to 8% by weight.
Description
technical field [0001] The present invention relates to a plasma display panel and a manufacturing method thereof. Background technique [0002] In recent years, flat panel displays such as plasma display panels (hereinafter, sometimes referred to as "PDP"), FEDs, and liquid crystal displays have attracted attention as displays capable of thinning and reducing weight. [0003] These flat panel displays include a front panel and a rear panel including a glass substrate and components arranged thereon. In addition, the front panel and the rear panel are arranged to face each other, and the outer peripheral parts are sealed. [0004] As described above, the PDP has a structure in which the front panel and the rear panel are opposed to each other, and their outer peripheries are sealed with sealing glass. The front panel includes a front glass substrate on which stripe-shaped display electrodes are formed, and furthermore, a dielectric layer and a protective layer are formed t...
