The present invention relates to a plasma display panel, and more
particularly, to an electrode structure of a plasma display panel capable
of improving brightness and efficiency. According to a first embodiment
of the present invention, in a plasma display panel of a long column
structure having a front substrate and a rear substrate that are opposite
to each other, the transparent electrodes of the scan electrodes or the
sustain electrodes include projections projected toward the center of the
discharge cells every discharge cell. Also, a discharge start voltage and
a discharge sustain voltage can be lowered and brightness and efficiency
can be increased. It is also possible to maintain color temperature
equilibrium every RGB cell and to reduce an erroneous discharge of each
cell.
