PURPOSE: A plasma address display device is provided to realize the lowering of a driving voltage by improving the driving system of plasma cells in which an AC type and a DC type are blended. CONSTITUTION: A plasma address display device has a flat panel in which display cells which are provided with columnar signal electrodes(Ys) and plasma cells which are provided with row-like discharge channels(Xs) are laminated and pixels(11) are provided at intersections of respective signal electrodes(Ys) and respective discharge channels(Xs), a scanning circuit(22) which selects pixels for every row by successively discharging the row discharge channels(Xs), a signal circuit(21) which writes a picture signal in pixels(11) of a selected row by successively supplying the picture signal to the columnar signal electrodes(Ys) in conformity with the discharge of the discharge channel(X). Each discharge channel(X) has a coated electrode(C) whose conductor surface is coated with a dielectric substance and an exposed electrode(B) whose conductor surface is not coated with a dielectric substance. After the scanning circuit(22) generates a preliminary discharge in the discharge channel(X) by holding the exposed electrode(B) to the ground potential and, on the other hand, by impressing a pulse on the coated electrode(C), the circuit generates a principal discharge in the channel by holding the coated electrode(C) to the ground potential and, on the other hand, by impressing the pulse on the exposed electrode(B) and thus, the circuit makes it possible to perform the lowering of the driving voltage. Moreover, the impression order of the pulse may be exchanged in both electrodes(B, C). |
