Abstract
Disclosed is a matrix display device comprising: a matrix display panel having a plurality rows of row electrodes and a plurality column of column electrodes and a display medium interposed therebetween, crosspoints of the row electrodes and the column electrodes defining picture cells arranged in matrix, each column of the column electrodes opposing to respective one column of the matrix picture cells being divided into a plurality of groups with a predetermined regularity and electrically interconnected within each group, terminals of at least two groups of column electrodes of the plurality of groups of column electrodes being arranged to extend to the same side of the matrix display panel; a row electrode drive circuit for producing row electrode drive signals to be applied to the row electrodes in accordance with a video data; a column electrode drive circuit for producing column electrode drive signals to be applied to the at least two groups of column electrodes in accordance with the video data; a video data circuit for supplying said video data to said row electrode drive circuit and said column electrode drive circuit. In the device, the outputs of the column electrode drive circuit or the video data to be supplied to the column electrode drive circuit are arranged in the same order as the arrangement of the terminals of the at least two groups of column electrodes.
