Abstract
A plasma display device is disclosed. The plasma display device has a first panel and a second panel parallel to each other. A dielectric layer is formed on the second panel, a plurality of barrier ribs are formed on the dielectric layer, and a plurality of buffer layers are formed opposite to the barrier ribs. The buffer layers have a first softening temperature, the barrier ribs have a second softening temperature, and the first softening temperature is lower than the second softening temperature. The buffer layers can be deformed and compressed at a temperature higher than the first softening temperature during a process for sealing the first and second panels, so as to unify heights of the barrier ribs.
