A display device comprising a display panel, a plasma driving circuit, a correcting circuit and a display driving circuit. The display panel has a laminated structure consisting of a display cell with signal electrodes arrayed in columns, a plasma cell with discharge channels arrayed in rows, and a dielectric sheet interposed therebetween. The plasma driving circuit sequentially drives the discharge channels to address the display cell line-sequentially via the dielectric sheet, and the correcting circuit processes picture signals through a corrective arithmetic operation. And the display driving circuit supplies the processed picture signals to the signal electrodes in synchronism with the line-sequential addressing, and then writes the picture signals in pixels prescribed at the intersections of the signal electrodes and the discharge channels. The correcting circuit executes such a process as to emphasize the difference between the picture signals supplied to mutually adjacent signal electrodes. This display device is adapted to eliminate, in driving the plasma addressed display panel, inter-pixel crosstalk or data diffusion derived from the thickness of the dielectric sheet.
