Embodiment Construction

[0033] FIG. 1A is a perspective view of main parts of an AC surface discharge type plasma display panel (PDP) according to an embodiment of the present invention. 1B and 1C are detailed views of the discharge electrode portion of the PDP, respectively. FIG. 1B is a cross-sectional view of the PDP along line 1B-1B in FIG. 1A, and FIG. 1C is a cross-sectional view of the PDP along line 1C-1C in FIG. 1A. For the sake of convenience, these figures show only three units, but actually the PDP has a plurality of units arranged to emit red (R), green (R), and blue (B) colored light.

[0034] As shown in FIGS. 1A to 1C , in the PDP of the embodiment, the front panel 10 and the rear panel 20 are bonded together, and a discharge gas is enclosed in the discharge space 30 formed between the front panel 10 and the rear panel 20 .

[0035] In the front panel 10, a plurality of discharge electrodes 12 are formed on the front glass substrate 11 which is made by the float process and has a meta...

Abstract

A glass substrate containing Na or K and being fabricated by a floating method has a surface coated with a metal oxide layer having a thermal expansion coefficient close to that of the glass substrate. Ag electrodes are provided on the metal oxide layer. This provides a plasma display panel with high image quality since the panel is prevented from migration of Ag between electrodes, thus having the glass substrate prevented from being tinted yellow. As a result, the plasma display panel at high quality can be implemented using the glass substrate.

Description

technical field [0001] The present invention relates to a plasma display panel (PDP) used as a display device or the like and a method of manufacturing the same. Background technique [0002] In recent years, expectations for high-quality, large-screen televisions represented by high-definition televisions have been increasing. In terms of clarity and image quality, cathode ray tubes (CRTs) are inferior to plasma displays and liquid crystal displays. Superior, but in terms of thickness and weight, it is not suitable for large screens over 40 inches. In addition, although liquid crystal has the superior performance of low power consumption and low driving voltage, the screen size and viewing angle are limited. Unlike the above, the plasma display can realize a large screen, and a 40-inch-class product has been developed (for example, Functional Materials, February 1996, Vol.16, No.2, page 7). [0003] The configuration of a conventional plasma display panel (PDP) and the co...
