There is provided a PDP and an
image display apparatus equipped with the same, in which the deterioration in the address
discharge timelag with age is suppressed, which is bright, has guaranteed life, can stably be driven, is of low
power consumption,
high definition, and high
image quality. There is provided a pair of sustaining
discharge electrodes on the front substrate extending in a row direction for forming a display line, a
floating electrode not connected to an external
electrode is arranged on the same substrate as the pair of sustaining
discharge electrode so as not to pass through a center line extending in a column direction and dividing the discharge
cell into two equal parts, thereby intensifying the local potential of an area of the MgO surface not influenced by the
sputtering by the sustaining discharge in the address discharge, promoting the
electron emission from this area, and suppressing the deterioration of the address discharge timelag.
