ABSTRACT:
A plasma addressed liquid crystal display device which includes a flat panel composed of a liquid crystal cell having signal electrodes in a column superposed on a plasma cell having discharge channels in a row. The discharge channel includes a pair of discharge electrodes for generating a plasma discharge therebetween; a scan control circuit for generating a strobe pulse for selecting the discharge channel; means for providing a first voltage pulse having one polarity with respect to a reference potential to one of the pair of electrodes; a constant current circuit for maintaining a discharge current at a constant level during discharge selection period; and driving means for providing a second voltage pulse to the other of the pair of the electrodes, the second voltage pulse having an initial potential of reversed polarity of the one polarity at the start of the discharge selection period, the potential decrementing with the lapse of time and returning to the reference potential before the end of the discharge selection period.
