Problems solved by technology

[0005] However, the transparent electrode formed by firing a dispersion of fine particles containing metal has disadvantages such as weak mechanical strength, easy peeling, and easy damage compared with indium tin oxide (ITO) thin films formed by sputtering.
Therefore, when simply replacing it with an indium tin oxide (ITO) thin film, there is a problem that the yield drops significantly.

Abstract

Provided is a plasma display panel which has transparent electrodes of a low cost without reducing yields. The plasma display panel comprises a first bus electrode and a second bus electrode mounted on a front substrate, a first transparent electrode mounted on the front substrate and covering at least a portion of the first bus electrode, and a second transparent electrode mounted on the front substrate and covering at least a portion of the second bus electrode.

Description

technical field [0001] The present invention relates to an AC surface discharge type plasma display panel used in a display device and a method for manufacturing the same. Background technique [0002] In an AC surface discharge type panel typified by a plasma display panel (hereinafter, simply referred to as a “panel”), a plurality of discharge cells are formed between a front panel and a rear panel that are arranged to face each other. The front panel has a front substrate made of glass, display electrode pairs including a pair of scan electrodes and sustain electrodes, a dielectric layer and a protective layer covering the display electrode pairs. The rear plate has a rear substrate made of glass, data electrodes, a dielectric layer covering the data electrodes, partition walls, and phosphor layers. Then, the front plate and the rear plate are arranged to face each other and sealed so that the display electrode pairs and the data electrodes form a three-dimensional inter...
