PURPOSE:To prevent the erasure of a picture, by sorting only boundary electrodes as same-order electrodes belonging to odd-numbered and even-numbered blocks, and by connecting the electrodes of each of the blocks to each other, so that each already lit display cell on the boundary line of the block is not deprived of wall charge due to the erasure address discharge of a totally lit display preparation cell adjacent to the former. CONSTITUTION:Among pairs of keeping electrodes constituting the display cells of a surface-discharge-type panel, in which the display cells are separated from selection cells, a plurality of one-side keeping electrodes x11, x12, x13 adjacent to each other are connected to each other in one electrode block. Such keeping electrodes are sequentially divided into a plurality of electrode blocks. Other-side keeping electrodes y3a1, y3b1,... located on the boundaried between the electrode blocks and belonging to pairs of outermost keeping electrodes are divided into odd-numbered and even-numbered blocks so that the other-side keeping electrodes of each of the blocks are connected to each other at Y3A, Y3B,.... An offsetting pulse Sa for offsetting the influence of an erasure preparation pulse Ax can be applied to the other-side keeping electrode y3a1, y3b1 or the like on the outermost line of the odd-numbered or even-numbered block during an erasure address preparation period BSS. |
