ABSTRACT:
An image display device capable of causing an interval between picture cells to be significantly decreased using control electrode means of a simple structure, to thereby provide a displayed image with high resolution. In the device, two control electrode groups are arranged in directions across each other, wherein the respective pairs of control electrodes in one of the control electrode groups are scanned in turn. The respective adjacent three or more control electrodes of the other groups are divided into sets, in which the respective pairs of the control electrodes are driven in turn in synchronism with the scanning.
