ABSTRACT:
In a gas-discharge display device, a plurality of parallel cathodes connected to cathode terminals (K.PHI..sub.1 to K.PHI..sub.4) by multiphase connection are disposed in equally spaced apart relation on one surface of a substrate, while a plurality of parallel and equally spaced-apart anodes are disposed on the rear surface of a face plate in a relation crossing with the cathodes, and the fact plate is superposed on the substrate through barrier ribs defining a discharge space. In the display device, time-serial multiphase pulse voltage trains are applied to the individual cathodes respectively, while a train of pulses of large width corresponding to display information is applied to each of the anodes in a relation superposed on a train of pulses of small width used for initiation of an auxiliary discharge.
