Problems solved by technology

[0018] However, the conventional PDP has the problem that since the metal bus electrodes 6-1B and 6-2B are formed on the upper portion of the discharge space of each cell, part of the visible light emitted in the discharge space is blocked, which reduces the brightness and efficiency of the PDP.
[0019] In addition, the formation of the metal bus electrodes 6-1B and 6-2B on the upper portion of the discharge space of each cell also causes a problem of lowering the aperture ratio.

Abstract

A plasma display panel is disclosed which increases an aperture rate, facilitate alignment, makes a cell to be shown uniformly, minimizes an increase in capacitance and a reduction of a cell size, and shares a metal bus electrode. The plasma display panel includes: a plurality of discharge cells and a metal bus electrode (42B1) formed at an upper portion of a barrier rib (46B) formed to divide the plurality of discharge cells.

Description

technical field [0001] The present invention relates to a plasma display panel, and more particularly, to a plasma display panel capable of increasing the aperture ratio and facilitating calibration. Background technique [0002] Usually, a plasma display panel (PDP) displays characters or graphic images by exciting the phosphorescent material to emit light with 147nm vacuum ultraviolet (VUV) when a gas such as He+X3, N3+X3, H3+Ne+Xe is discharged. Achieved. Because PDP has the advantages of thin thickness and large area, it has attracted extensive attention as a large-scale flat panel display. [0003] Figure 1A and 1B Shows the structure of a 3-electrode alternating current (AC) type PDP according to the conventional art. [0004] As shown, the PDP includes a lower glass substrate 1; an address electrode 2 formed on a specific portion of the lower glass substrate 1; a lower dielectric layer 9 formed on the entire surface of the lower glass substrate 1 and the address e...
