Embodiment Construction

[0016] Describe the present invention in detail below by example and accompanying drawing.

[0017] FIG. 1 is a picture showing an example of the structure of a plasma display panel.

[0018] Referring to FIG. 1 , the plasma display panel includes scan electrodes 11 and sustain electrodes 12 as sustain electrode pairs formed on an upper substrate 10 and address electrodes 22 formed on a lower substrate 20 .

[0019] Usually, the pair of sustain electrodes 11, 12 are transparent electrodes 11a, 12a composed of indium tin oxide (Indium-Tin-Oxide; ITO) respectively, and metals such as silver (Ag), chromium (Cr) or chromium / The bus electrodes 11b, 12b are formed of a copper / chrome (Cr / Cu / Cr) layered type or a chromium / aluminum / chrome (Cr / Al / Cr) layered type.

[0020] At this time, the bus electrodes 11b, 12b are formed on the transparent electrodes 11a, 12a to reduce the voltage drop caused by the transparent electrodes 11a, 12a having higher resistance.

[0021] Moreover, a bl...

Abstract

A plasma display apparatus is provided to suppress a breakdown of a sustain electrode by expanding a coated region of an upper dielectric wider than a sealed region of a sealing agent. A first electrode, a second electrode, and a dielectric layer are formed on an upper surface of an upper substrate(110). A third electrode is formed across the first and second electrodes on a lower substrate(120). The upper substrate and the lower substrate are attached to each other by using a sealing agent. The dielectric layer has an expanded region in comparison with a sealed region of the sealing agent. A gap between an outermost part of the dielectric layer and an outermost part of the sealed region of the sealing agent is 0.1mm to 10.0mm.

Description

technical field [0001] The present invention is an invention related to a plasma display device, especially a plasma display device that prevents bus electrodes from being damaged by forming an upper dielectric layer on an upper substrate at certain intervals to prevent bus electrodes formed on the upper substrate from being exposed. Background technique [0002] Usually, a plasma display panel (Plasma Display Panel, hereinafter referred to as PDP) is to cause a discharge by applying a certain voltage to each electrode in the discharge space, and the plasma generated during the gas discharge excites the phosphor to display text or images including graphs. device. The plasma display panel has the advantages of easy enlargement, light weight and plane thinning, and can provide wide viewing angles of up, down, left, and right, and display full color and high brightness. [0003] In this type of PDP, the end regions of the scan electrodes and the sustain electrodes formed on th...
