1. An electrochemical display comprising:

  • first and second electrode layers having different electrode potentials;

    an electrolyte layer overlapping said first electrode layer and forming a boundary with said second electrode layer for completing an ionically conductive pathway between said first and second electrode layers; and

    said electrolyte boundary being movable together with a boundary of said second electrode layer extending the ionically conductive pathway from said first electrode layer in response to a flow of current between said first and second electrode layers for changing a visible appearance of the display.
