Abstract:
An AC type plasma display comprising:first and second substrates disposed oppositely; scan electrodes and sustainment electrodes provided alternately at an opposite face side to said second substrate in said first substrate, said scanning and sustainment electrodes extending in a row direction; date electrodes provided at an opposite face side to said first substrate in said second substrate, said date electrodes extending in a column direction; and auxiliary electrodes provided at all of spaces between said scan electrodes and said sustainment electrodes, said auxiliary electrodes extending in a row direction; a driving device; wherein said driving device in each sub-field that configures a first frame: holds a potential of auxiliary electrodes disposed at descending odd numbers at an arbitrary bias potential between a sustainment voltage applied to said sustainment electrodes during a sustainment discharge and a grounding potential at least during an addressing period, and applies a signal identical to a driving signal to be applied to one electrode selected from the group comprising said sustainment electrodes and scan electrodes to said auxiliary electrode disposed at the descending even numbers, and wherein said driving device in each sub-field that configures a second frame: holds a potential of said auxiliary electrode disposed at even numbers at said arbitrary bias potential at least during said addressing period, and applies said signal identical to a driving signal to be applied to said one electrode to said auxiliary electrode disposed at odd numbers.
