Abstract
A sheet-like display medium includes a switching layer containing a switching material having a light absorption spectrum which changes in a visible light range when a voltage no less than a threshold value is applied while also maintaining the changed light absorption spectrum even after the voltage application is interrupted, and an electrode layer laminated on the switching layer. The switching material may be an organic metal complex such as Cu-TCNQ or Ag-TCNQ.
Claims22
A sheet-like display medium comprising:
- a switching layer containing a switching material having a light absorption spectrum which changes in a visible light range when a voltage no less than a threshold value is applied while also maintaining the changed light absorption spectrum even after the voltage application is interrupted;
- and
- an electrode layer laminated on the switching layer.
A display element comprising:
- an anode layer;
- a cathode layer;
- and
- a switching layer disposed between the anode layer and the cathode layer, the switching layer containing a switching material having a light absorption spectrum which changes in a visible light range when a voltage no less than a threshold value is applied while also maintaining the changed light absorption spectrum even after the voltage application is interrupted.
A display device comprising a plurality of display elements arranged in a matrix including a plurality of rows and a plurality of columns;
- the plurality of display elements including a common switching layer, a plurality of first electrode lines formed on one surface of the switching layer correspondingly to the rows of the matrix, and a plurality of second electrode lines formed on an opposite surface of the switching layer correspondingly to the columns of the matrix;
- the switching layer containing a switching material having a light absorption spectrum which changes in a visible light range when a voltage no less than a threshold value is applied while also maintaining the changed light absorption spectrum even after the voltage application is interrupted.
