Abstract
A display system is built up of at least one display cell comprising an assembly which has at least a first electrode and a second electrode and in which there are mutually non-miscible first and second liquids filled, wherein either one of the first and second electrodes is electrically insulated from the first and second liquids, the first liquid has electrical conductivity or polarity, and voltage is applied to one or both of the first and second electrodes, whereby the first liquid and the second liquid can vary in position to produce a display. Even after an applied voltage is shut off at a position to which the first and second liquids have migrated, the positions of the first and second liquids that have migrated are retained to keep memory capability going on.
