PROBLEM TO BE SOLVED: 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. SOLUTION: This plasma address display device has a flat panel 10 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 comformity 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. |
