A gas-discharge display device has a parallel array of anodes and a parallel array of cathodes forming a matrix of anode-cathode cross points or discharge dots. The display device is filled with a discharge gas mixture at the discharge dots or cells. Displaying and scanning are respectively achieved through drive circuits supplying discharges of a layer and a smaller current, or discharges for a longer and shorter time respectively.
