Patent attributes
A plasma display device having an improved electrode structure that is capable of improving a contrast of the plasma display panel while decreasing a discharge firing voltage is provided. A plasma display panel according to an embodiment of the invention includes first and second substrates disposed 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, address electrodes formed along a first direction, and display electrodes formed along a second direction intersecting the first direction. The display electrodes include bus electrodes formed extending in the second direction, expansion electrodes that extend toward the center of each discharge cell from the bus electrodes and face each other in the discharge cell with a discharge gap interposed therebetween, and auxiliary electrodes located at front ends of the expansion electrodes opposite to each other.
