Abstract
A display device () includes an upper substrate (first substrate) (), a lower substrate (second substrate) (), and a conductive liquid () that is sealed in a display space (S) formed between the upper substrate () and the lower substrate () so as to be moved toward an effective display region (P) or a non-effective display region (P). The display device () includes a signal electrode (), a reference electrode (), and a scanning electrode (). An M voltage (intermediate voltage) between an H voltage (first voltage) and a L voltage (second voltage) and a voltage other than the M voltage are applied to the signal electrode () within a selected period (predetermined period) T during which one of the H voltage and the L voltage is applied to the reference electrode ().
