Embodiment approach

[0052] figure 1 It is a perspective view showing the structure of the PDP in the embodiment of the present invention. figure 2 It is a perspective view showing a front panel and a rear panel separately. image 3 is a cross-sectional view showing the cross-sectional structure of the discharge cell portion.

[0053] Such as figure 1 As shown, the PDP 1 is arranged such that a front panel 2 including a front glass substrate 3 and the like faces a rear panel 10 including a rear glass substrate 11 and the like. The outer peripheral portion of the PDP 1 is sealed with a sealing material made of glass frit or the like. Discharge gases such as Ne and Xe are sealed in the discharge space 16 inside the sealed PDP 1 at a pressure of 400 Torr to 600 Torr.

[0054] 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 arrange...

Abstract

A plasma display panel is provided with a front substrate which has a dielectric layer formed to cover a display electrode formed on a front glass substrate, and has a protection layer formed on the dielectric layer; and a rear substrate, which is arranged to face the front substrate so as to form a discharge space and to form an address electrode formed in a direction that intersects the display electrode, and is provided with a plurality of vertical barrier ribs and horizontal barrier ribs which are arranged parallel to the address electrode. The protection layer forms a base film on the dielectric layer, and the protection layer is configured by adhering a plurality of crystal grains composed of a metal oxide such that the crystal grains are distributed over the entire surface of the base film. The barrier ribs are configured such that the horizontal barrier ribs are lower than the vertical barrier ribs.

Description

technical field [0001] The present invention relates to a plasma display panel used in a display device and the like. Background technique [0002] Plasma display panels (hereinafter referred to as "PDP") are widely used in 65-inch type televisions and the like because they can achieve high definition and large screen size. In recent years, compared with the existing NTSC system, PDP has been developed to be suitable for high-definition televisions with twice or more scanning lines, and in consideration of environmental issues, lead-free PDPs are required. [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 consisting of stripe-shaped transparent electrodes and bus electrodes formed on one main surface of the glass substrate; a dielectric layer, which covers the display electrodes and functions as a capacitor; and a protective laye...
