Abstract
A plasma display panel (PDP) is capable of directly and effectively removing impurities from a discharging space for enhancing the purity of a discharging gas. The PDP has a getter layer formed of at least a portion of a barrier rib. The getter layer is independently formed at an upper portion of each barrier rib with respect to each discharging cell or maybe formed to cross each other at every other cell with respect to the discharging cells formed in a direction in which the barrier ribs extend. The getter material particles are dispersed in an insulation material so that the getter layer has an electrical insulation characteristic.
Claims8
A plasma display panel (PDP) comprising an upper substrate and a lower substrate which are parallel to each other at a certain distance, a plurality of barrier ribs formed on the lower substrate for forming a discharging space, a plurality of address electrodes formed between each barrier rib, a plurality of display electrodes pairs formed on a surface of the upper substrate opposite to the lower substrate and crossing with the address electrodes, a plurality of discharging cells formed on at crossing portions between the address electrodes and the display electrodes, phosphor layers formed on at least a portion between each of the barrier ribs, and a discharging gas tightly filled in the discharging space between the upper substrate and the lower substrate, being characterized in that a getter layer is formed on at least one portion of the barrier ribs.
