Problems solved by technology

[0007] However these extended electrodes do not have high conductivity, resulting in high discharge ignition voltage
[0008] Also, there have been reports that ambient light reflected from the front substrate of a PDP degrades the contrast ratio in the PDP

Abstract

The present invention provides a plasma display device having an improved electrode structure capable of improving the contrast of a plasma display panel and reducing a discharge firing voltage. A plasma display panel according to an embodiment of the present invention includes a first substrate and a second substrate placed opposite to each other, barrier ribs arranged in a space between the first substrate and the second substrate to define at least one discharge cell, along Address electrodes formed in a first direction and display electrodes formed in a second direction crossing the first direction. The display electrode includes a bus electrode formed extending in the second direction, extension electrodes extending from the bus electrode toward the center of each discharge cell and facing each other in the discharge cells with a discharge gap interposed therebetween, and extended electrodes disposed in the discharge cells. The front ends of the extended electrodes and the auxiliary electrodes facing each other.

Description

technical field [0001] The present invention relates to a plasma display panel, in particular, to a plasma display panel with an improved electrode structure. Background technique [0002] In general, a plasma display panel (hereinafter referred to as PDP) is a display device in which vacuum ultraviolet (VUV) emitted from plasma generated by gas discharge excites phosphors to emit visible light, thereby forming a predetermined image. [0003] PDPs can be manufactured as large screens with a thickness of less than 10 cm and a diagonal of more than 60 inches. Since it is a self-emissive display device, like a cathode ray tube display, there is no distortion due to viewing angle, and it has outstanding color reproduction. In addition, its manufacturing process is simpler than that of a liquid crystal display device, and thus the PDP has advantages in manufacturability and cost. Accordingly, PDPs have been proposed as next-generation flat panel displays and televisions for ind...
