Embodiment Construction

[0040] refer to Figure 9 , The plasma display panel (PDP) according to the first embodiment of the present invention includes: a pair of sustain electrodes Y and Z positioned on an active area 91 on which an image is displayed; and upper dummy electrodes DUE1 and DUE2 and lower dummy electrodes BDE1 and BDE2 , the gap g1 between the electrodes is smaller than the gap between the pair of sustain electrodes Y and Z on the active area 91, and there is a narrow width w1 between the electrodes. Upper dummy electrodes UDE1 and UDE2 are formed on the upper non-display area 92 , and lower dummy electrodes BDE1 and BDE2 are formed on the lower non-display area 93 .

[0041] Such as Figure 10 As shown, each of the sustain electrode pair Y and Z, the dummy electrodes UDE1 and UDE2 and the lower dummy electrodes BDE1 and BDE2 includes: a transparent electrode 10; and a metal bus electrode 12 formed on the edge of the transparent electrode 10 with a line width of Narrower than the line...

Abstract

A plasma display panel having an active area and a non-display area positioned at the outside of the active area wherein dummy electrodes positioned within said non-display area have a narrower gap between electrodes than sustain electrode pairs positioned within said active area. Accordingly, the plasma display panel has a narrower gap between electrodes of the dummy electrodes than the sustain electrode pair within the active area and has a narrow electrode width thereof, so that it can easily generate a discharge between the dummy electrodes well and reduce a generation of electric charges accumulated onto the dummy electrodes. As a result, the plasma display panel can prevent an abnormal discharge to improve a picture quality.

Description

technical field [0001] The present invention relates to a plasma display panel, and more particularly, to a plasma display panel adapted to prevent abnormal discharge from a non-display area, thereby improving image quality and reliability. Background technique [0002] Generally, a plasma display panel (PDP) utilizes an inert mixed gas discharge such as helium (He) + xenon (Xe), neon (Ne) + xenon (Xe) or helium (He) + neon (Ne) + xenon (Xe) When the ultraviolet light generated excites or irradiates the fluorescent material to display the image. Such PDPs are arbitrarily manufactured as thin-film, large-size displays. In addition, PDP is currently available in the market, and has a high share in the large-size flat panel display market. [0003] refer to figure 1 , the discharge cell of a conventional three-electrode, AC surface-discharge PDP includes a sustain electrode pair having a scan electrode Y and a sustain electrode Z disposed on an upper substrate 1, and an addr...
