Abstract
A plasma display device includes plasma display panel and a data driver. Plasma display panel includes a front substrate and a rear substrate faced to each other to form a discharge space therebetween. The front substrate includes a plurality of display electrodes, each having scan electrode and sustain electrode. The rear substrate includes a plurality of data electrodes intersected with the display electrodes. Discharges cells are formed at the intersections of the display electrodes and data electrodes. Data electrodes have a plurality of main electrode parts) formed in portions facing the display electrodes, and wiring parts that connect main electrode parts and have a width smaller than the widths of main electrode parts. Further, the corner of main electrode part is chamfered.
Claims3
A plasma display device comprising:
- a plasma display panel including:
