ABSTRACT:
A gas discharge display apparatus includes a substrate on which a number of electrodes are formed in a row with a distance therebetween and interconnected through polyphase connections. Bipolar pulse voltages are sequentially applied to each phase of the polyphase connections to thereby cause each of the electrodes to operate alternately as an anode and a cathode on a time division basis, whereby discharge produced between the anode and the cathode is caused to perform self-scanning.
