Patent ID: 7274145

Claim:
A plasma display panel, comprising: a first substrate having a vacuum hole disposed in said first substrate; a second substrate paralleled with said first substrate so as to define a discharge space between said first substrate and said second substrate; a plurality of elongated electrodes formed on said first substrate and each elongated electrode extends in a first direction; and a grid-mesh-shaped barrier rib formed on said elongated electrodes, wherein said grid-mesh-shaped barrier rib comprises: a shaped layer wherein said shaped layer comprises a plurality of first stripe ribs along a first direction which separate said discharge space into a plurality of sub discharge spaces; and a plurality of second stripe ribs intersecting said first stripe rib areas, wherein each of said second stripe ribs defines a channel, and the depth of the channel is deeper than that of the discharge space; and a plurality of bumps with a thickness formed on said shaped layer to define passages between said first substrate and said second substrate, wherein said passages are communicated with said discharge space.
