Problems solved by technology
Therefore, problems arise because the discharge spreads poorly
[0016] In the existing fence-type electrode structure, the aspect ratio is low and the discharge spread is poor
Therefore, there is a problem that the luminance and discharge efficiency of the plasma display panel are low

Embodiment Construction
[0053] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0054] image 3 is a plan view of a plasma display panel according to an embodiment of the present invention. Such as image 3 As shown, the plasma display panel according to the present invention includes a discharge cell 290 , an upper electrode portion 305 , a lower electrode portion 310 , a first center electrode portion 315 and a second center electrode portion 320 .
[0055] The discharge cells 290 are partitioned by the barrier ribs 300, and provide a space in which a discharge is generated by an inert gas therein.
[0056] The upper electrode part 305 and the lower electrode part 310 are formed adjacent to the boundary of the discharge cell 290, and the first driving pulse is supplied thereto. The upper electrode part 305 and the lower electrode part 310 serve as one of scan electrodes and sustain electrodes. Therefore, if the upper elect...

Abstract
The present invention relates to a plasma display panel and a plasma display apparatus, and more particularly, to a plasma display panel and plasma display apparatus comprising electrodes. The plasma display panel according to the present invention comprises discharge cell partitioned by barrier ribs, upper electrode part and lower electrode part formed adjacent to the boundary of the discharge cell and applied with a first driving pulse, first center electrode part located between the upper electrode part and the lower electrode part and applied with a second driving pulse, and second center electrode part located between the first center electrode part and the lower electrode part and applied with the second driving pulse. According to the present invention, brightness and discharge efficiency can be improved since a discharge amount is increased and discharge diffusion is easily performed.
Description
[0001] Cross References to Related Applications [0002] This application claims priority from Patent Application Nos. 2004-81127 and 2004-81128 filed in Korea on October 11, 2004, the entire contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to a plasma display panel and a plasma display device, and more particularly, to a plasma display panel and a plasma display device including electrodes. Background technique [0004] Generally, a plasma display panel includes a front substrate and a rear substrate composed of soda lime glass. Barrier ribs formed between the front substrate and the rear substrate partition a plurality of discharge cells. An inert gas such as helium-xenon (He-Xe) or helium-neon (He-Ne) is injected into the discharge cell, and the inert gas is excited with a high-frequency voltage to generate a discharge. When a discharge is generated, vacuum ultraviolet rays are generated. T...
