ABSTRACT:
A recording device that includes an obtainment unit that obtains image information representing an image; and a voltage application unit that applies a voltage with a frequency according to the image information obtained by the obtainment unit, to a pair of electrodes equipped with a display medium, the display medium having a multi-layered liquid-crystal phase provided between the pair of electrodes, the multi-layered liquid-crystal phase having a first layer capable of assuming a specific alignment when the applied voltage is greater than or equal to a pre-set first voltage threshold, and a second layer capable of assuming a specific alignment when the applied voltage is greater than or equal to a second voltage threshold. An application of a voltage to the pair of electrodes effecting a first voltage component and a second voltage component applied to the first layer and the second layer, respectively.
