ABSTRACT:
A gas discharge display device including a display panel in which a discharging space between a transparent front plate and a rear plate is partitioned by a large number of long and thin dielectric partitions, and discharge cells are provided in solid crossing portions of stripe-shaped anodes each intervening between a pair of the dielectric partitions and stripe-shaped cathodes arranged in a direction intersecting the anodes, and a third electrode covered with a dielectric layer is provided at the rear side of the cathodes and further a reset electrode is provided in a region contiguous to the cathodes, wherein a voltage enough to cause a displaying discharge is applied to predetermined anodes to cause displaying discharges in a period when the cathodes are serially scanned, and further an electric potential of the third electrode is changed to make the dielectric layer store electric charge during a vertical blanking interval in which the cathodes are not scanned, and moreover scanning discharges are caused between the stored charges and the cathodes during the cathodes are serially scanned, and wherein an electric potential of the reset electrode is changed in a period from a moment, at which an electric potential of the third electrode is changed, to another moment, at which the serial scan of the second electrodes is commenced, so that a reset discharge is caused between the reset electrode and each of the anodes and thus an electric potential of the anodes is made to have a predetermined value.
