Problems solved by technology

In this way, there is a problem that it is necessary to have the following two opposite functions: as a characteristic of the protective layer, it not only has high electron emission performance, but also has the function of reducing the amount of attenuation of the charge that functions as a memory, that is, has a high charge retention. performance

Embodiment approach

[0030] figure 1 It is a perspective view showing the structure of the PDP in the embodiment of the present invention. The basic structure of the PDP is the same as that of a common AC surface discharge type PDP. Such as figure 1 As shown in the PDP 1, a front panel 2 composed of a front glass substrate 3 and the like and a rear panel 10 composed of a rear glass substrate 11 and the like are opposed to each other. The outer peripheral portion of the PDP 1 is hermetically sealed by a sealing material made of glass frit or the like. Discharge gas such as Ne and Xe is sealed at a pressure of 400 Torr to 600 Torr in the discharge space 16 inside the hermetically sealed PDP 1 .

[0031] On the front glass substrate 3 of the front panel 2, a plurality of display electrodes 6 composed of a pair of strip-shaped scan electrodes 4 and sustain electrodes 5 and black stripes (light shielding layers) 7 are arranged in parallel to each other. A dielectric layer 8 functioning as a capac...

Abstract

Disclosed is a plasma display panel comprising a front plate wherein a dielectric layer is so formed as to cover a display electrode formed on a front glass substrate and a protective layer is formed on the dielectric layer, and a back plate so arranged as to face the front plate so that a discharge space is formed therebetween. The back plate is provided with an address electrode lying in the direction intersecting the display electrode and a partition wall which divides the discharge space. The protective layer is obtained by forming a base film on the dielectric layer, and having agglomerated particles, wherein a plurality of crystal particles composed of a metal oxide are agglomerated, adhere to the base film in such a manner that the agglomerated particles are distributed all over the base film. The number of the agglomerated particles adhering the base film is set at not less than 45 but not more than 350 per 10,000 [mu]m2 of the base film.

Description

technical field [0001] The present invention relates to a plasma display panel used in a display device or the like. Background technique [0002] A plasma display panel (hereinafter referred to as "PDP") is used in the production of 65-inch-class televisions and the like because it can achieve high definition and large screen size. In recent years, PDP has not only been used in high-definition televisions with more than twice the number of scanning lines compared to the conventional NTSC system, but also PDPs that do not contain lead have been demanded in consideration of environmental protection. [0003] A PDP basically consists of a front panel and a rear panel. The front panel is composed of a glass substrate of sodium borosilicate glass based on a float process, display electrodes composed of stripe-shaped transparent electrodes and bus electrodes formed on one main surface of the glass substrate, covering the display electrodes and serving as A dielectric layer that...
