Abstract

A honeycomb type plasma display panel has a honeycombed barrier rib structure which defines a plurality of cells, and a plurality of scan electrodes and a plurality of maintain electrodes arranged alternately in a first direction. Each scan electrode has a first bus electrode and a plurality of first protrusions, and each maintain electrode has a second bus electrode and a plurality of second protrusions. The first bus electrodes, the first protrusions, the second bus electrodes, and the second protrusions are metal electrodes.
