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...
