DISPLAY MEDIUM
First Claim
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.

Abstract
A display medium comprises: 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 contains 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. 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.
