Problems solved by technology

However, when impurities are mixed in the protective layer to improve electron emission performance, charges are accumulated on the surface of the protective layer at the same time, and the attenuation rate of charge reduction over time when used as a memory function increases.

Embodiment approach

[0049] figure 1 is a side view showing the structure of the PDP according to 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, the front panel 2 including the front glass substrate 3 and the like and the rear panel 10 including the rear glass substrate 11 and the like are disposed opposite to each other. The outer peripheral portion of the PDP 1 is hermetically sealed with a sealing material including glass frit or the like. Discharge gas such as Ne and Xe is sealed in the discharge space 16 inside the sealed PDP 1 at a pressure of 400 Torr to 600 Torr.

[0050] A pair of strip-shaped display electrodes 6 and black strips (light shielding layers) 7 composed of scan electrodes 4 and sustain electrodes 5 are arranged in parallel on front glass substrate 3 of front panel 2 in multiple rows. A dielectric layer 8 functioning as a capacitor is formed on t...

Abstract

A plasma display panel includes a front panel including a glass front substrate, a display electrode formed on the substrate, a dielectric layer formed so as to cover the display electrode, and a protective layer formed on the dielectric layer; and a rear panel disposed 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 partitioning the discharge space. The protective layer is formed by forming a base film on the dielectric layer and attaching a plurality of crystal particles made of metal oxide to the base film so as to be distributed over an entire surface at a covering rate of not less than 1% and not more than 15%.

Description

technical field [0001] The present invention relates to a plasma display panel used for a display device or the like. Background technique [0002] A plasma display panel (hereinafter referred to as "PDP") is used as a 65-inch-class television or the like because it can achieve high definition and a large screen. In recent years, PDPs have been gradually applied to high-definition televisions that have more than twice the number of scanning lines compared to the current NTSC system, and lead-free PDPs are required in consideration of environmental issues. [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 obtained by a float process, a display electrode composed of strip-shaped transparent electrodes and bus electrodes formed on one main surface of the glass substrate, The display electrodes are covered with a dielectric layer functioning as a capacitor and a protective layer co...
