1. A display medium comprising:

  • a pair of electrodes to which a voltage is applied; and

    a liquid crystal layer stack provided between the pair of electrodes, the liquid crystal layer stack containing a first liquid crystal layer having a first liquid crystal that undergoes transition into a specific alignment state in response to the voltage applied to the electrodes becoming equal to or greater than a first voltage value and a second liquid crystal layer having a second liquid crystal that undergoes transition into the specific alignment state in response to the voltage becoming equal to or greater than a second voltage value,wherein;

    the second voltage value is greater than the first voltage value; and

    the second liquid crystal has a higher isotropic phase transition temperature than the first liquid crystal.
