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.
