Patent ID: 8164823

Claim:
A display system built up of at least one display cell comprising: an assembly which includes 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 said first and second electrodes is electrically insulated from said first and second liquids, said first liquid has electrical conductivity or polarity, and voltage is applied to one or both of said first and second electrodes, whereby said first liquid and said second liquid vary in position to produce a display, and even after an applied voltage is shut off at a position to which said first and second liquids have migrated, positions of said first and second liquids that have migrated are retained to keep memory capability going on; and further comprising an intermediate partition for retaining the positions of said first and second liquids that have migrated, after the applied voltage is shut off at the positions of said first and second liquids that have migrated, wherein said assembly comprises a set of substrates, at least one of which is transparent, a wall portion for holding said set of substrates in opposition to one another in such a way as to define a liquid confining space, a 1 st -A electrode and a 1 st -B electrode that are located on one substrate that faces said liquid confining space in an electrically independent way, wherein the intermediate partition is located at a boundary site between said 1 st -A electrode and said 1 st -B electrodes to divide said liquid confining space in a direction along said substrate surface, and a second electrode that is located on another substrate that faces said liquid confining space, wherein said 1 st -A electrode and said 1 st -B electrode are electrically insulated from said first and second liquids, and wherein said intermediate partition includes an opening that defines a liquid flow path; at a voltage applied to said 1 st -A electrode and said second electrode or a voltage applied to said 1 st -B electrode and said second electrode, said second liquid passes through the opening in said intermediate partition to be able to migrate between on said 1 st A electrode and on said 1 st -B electrode.
