Problems solved by technology

In order to expand the discharge space while maintaining the image quality such as image resolution, it is necessary to increase the height of the partition wall. However, if the height of the partition wall is simply increased, there are strength problems such as uneven shape, partition wall chipping, and partition wall collapse.

Embodiment Construction

[0035] Embodiments of the present invention will be described below with reference to the drawings.

[0036] FIG. 1 is an exploded perspective view showing a configuration example of a plasma display panel according to one embodiment of the present invention.

[0037] On front glass substrate 10 , X electrodes (sustain electrodes) 11 and Y electrodes (scan electrodes) 12 for performing sustain discharge are arranged in parallel and alternately. A dielectric layer 13 made of low-melting glass or the like is covered thereon. Further, a protective layer 14 of MgO (magnesium oxide) is covered thereon. That is, the X electrodes 11 and the Y electrodes 12 arranged on the front glass substrate 10 are covered with the dielectric layer 13 , and their surfaces are covered with the protective layer 14 .

[0038] Address electrodes 16R, 16G, and 16B are formed on rear glass substrate 15 facing front glass substrate 10 in a direction perpendicular to (intersecting) X electrodes 11 and Y ...

Abstract

In a plasma display panel having a discharge gas sealed in a gap between a front side substrate and a rear side substrate opposed to each other and having ribs partitioning a gas-sealed space into a discharge cell array arranged above an inner surface of one of the substrates, the rib includes an upper-layer rib and a lower-layer rib, and the upper-layer rib and the lower-layer rib are made of rib materials different from each other in resistance to etching, thereby allowing for formation of high ribs to enlarge the discharge space without affecting the upper-layer ribs when forming the lower-layer ribs.

Description

technical field [0001] The present invention relates to a plasma display panel and a manufacturing method thereof. Background technique [0002] As a planar display device, a plasma display device having a plasma display panel (PDP: Plasma Display Panel) is being put into practical use, and pixels on a screen emit light according to display data. In a surface discharge type plasma display panel, a plurality of surface discharge electrodes are formed on the inner surface of a front glass substrate, and the surface discharge electrodes are covered with a dielectric layer and a protective layer. Partition walls were formed on the inner surface of the rear glass substrate, and phosphor layers in which red (R), green (G) and blue (B) phosphors of three primary colors were applied between the partition walls were formed. The surface discharge type plasma display panel has a structure in which the front glass substrate and the rear glass substrate are sealed, and a rare gas is sea...
