1. A method for driving a display panel having a first substrate, at least one display line involving first electrodes and second electrodes disposed in parallel with each other on said first substrate, a second substrate facing said first substrate, and third electrodes disposed on said second substrate and extending orthogonally to said first and second electrodes, in which a display by means of a light emission and write operation of display data are executed by carrying out a write discharge utilizing a memory function for cells of said at least one display line and by carrying out a sustain discharge for sustaining said write discharge, wherein said method includes:

  • a step of executing a write discharge for all cells of at least one display line selected by either one of said first and second electrodes and by said third electrode with use of said first and second electrodes; and

    a step of executing an erase discharge for all cells of said selected display line with use of said first and second electrodes, said two steps being adapted to be carried out before said write discharge utilizing said memory function is executed.
