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. In the discharge space 16 inside the sealed PDP 1 , discharge gases such as Ne and Xe are sealed at a pressure of 400 Torr to 600 Torr.

[0031] On front glass substrate 3 of 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 each other. A dielectric layer 8 functioning as a capacitor is formed on the front glass ...

Abstract

A plasma display panel including a front panel including front glass substrate 3, a display electrode formed on the substrate, a dielectric layer formed to cover the display electrode, and a protective layer formed on the dielectric layer; and a rear panel facing the front panel so that discharge space is formed and including an address electrode formed in a direction intersecting the display electrode, and a barrier rib for partitioning the discharge space. The protective layer includes a base film on the dielectric layer and aggregated particles of a plurality of aggregated metal oxide crystal particles attached to the base film so that they are distributed over an entire surface. The aggregated particles have distribution of peak intensity values in a spectrum in a wavelength range of not less than 200 nm and not more than 300 nm of a cathode luminescence within 240% of a cumulative average value.

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 whic...
