Patent ID: 7683545

Claim:
A plasma display panel comprising: a first substrate and a second substrate opposing each other; address electrodes extending in a first direction on the second substrate; barrier ribs arranged in the space between the first substrate and the second substrate to define a plurality of discharge cells; phosphor layers in the discharge cells ( 27 R, 27 G, 27 B); and display electrodes on the first substrate, the display electrodes having bus electrodes extending in a second direction crossing the first direction to form a corresponding pair of the display electrodes corresponding to each of the discharge cells ( 27 R, 27 G, 27 B), and extension electrodes individually extending from the bus electrodes to each of the discharge cells ( 27 R, 27 G, 27 B) to form an opposing pair of the extension electrodes, wherein a pair of the display electrodes corresponding to each of the discharge cells ( 27 R, 27 G, 27 B) forms a first gap and a second gap having different distances from each other between the extension electrodes opposing each other, and forms a third gap between the bus electrodes, wherein the second gap is longer than the first gap, and the third gap is longer than the second gap, wherein the barrier ribs further define a plurality of non-discharge regions, wherein at least two of the discharge cells ( 27 R, 27 G, 27 B) adjacent to one another in the first direction has a common non-discharge region of the plurality of non-discharge regions with another at least two of the discharge cells ( 27 R, 27 G, 27 B) adjacent to one another in the second direction, and wherein at least two adjacent non-discharge regions of the plurality of non-discharge regions share a common barrier rib of the barrier ribs, the at least two adjacent non-discharge regions being adjacent along the second direction, the common barrier rib extending in the first direction.
