Abstract
In a plasma addressed display device, rush currents flowing through the respective channels during a discharge starting time period are suppressed. A plasma addressed display device is comprised of: a plurality of data electrodes on a first substrate arranged in parallel to each other; a plurality of discharge electrodes on a second substrate each having an anode electrode and a cathode electrode arranged in parallel to each other and perpendicular to the data electrodes; a liquid crystal layer provided between the first substrate and the second substrate; a plurality of discharge channels formed between the liquid crystal layer and the second substrate, and containing ionized gas, each of the discharge channel having at least a pair of the anode electrode and the cathode electrode; a plurality of switching means for sequentially selecting the discharge channels, the switching means being provided in one-to-one correspondence with each of the discharge channels; a current supplying means for supplying a drive current to the discharge channels through the switching means corresponding to each of the discharge channels; and a control means for controlling the current supplying means in synchronization with a switching timing of the switching means, the drive current being intermittently supplied to the discharge channels by the control means.
