Patent ID: 7501760

Claim:
A plasma display device, comprising: a first substrate having a substantially planar surface; a second substrate opposing the first substrate; a plurality of barrier ribs that are located between the first substrate and the second substrate to partition a plurality of discharge cells, the plurality of barrier ribs comprising a first barrier rib and a second barrier rib; wherein the first barrier rib provides a first sidewall to a first one of the discharge cells, and the second barrier rib provides a second sidewall to the first discharge cell; wherein one or more additional barrier ribs provide the first discharge cell with one or more additional sidewalls, wherein each additional barrier rib has a height, which is the length thereof in a third direction, and wherein the height of each additional barrier rib is greater than the second height; wherein the first barrier rib extends generally in a first direction substantially parallel to the substantially planar surface and has a first height, which is the length of the first barrier rib in the third direction perpendicular to the substantially planar surface; wherein the second barrier rib extends generally in a second direction substantially parallel to the substantially planar surface and has a second height, which is the length of the second barrier rib in the third direction; and wherein the first height is greater than the second height.
