Abstract
A writing device includes: a display medium including: a first display layer; a second display layer stacked on the first display layer; a first conductive layer and a second conductive layer sandwiching the first display layer and the second display layer; and a photosensitive layer located between the first conductive layer and the second conductive layer; a voltage-applying unit that applies a bias voltage to the first conductive layer and the second conductive layer, a frequency of the bias voltage differing between a case in which a state of the first display layer and a state of the second display layer are changed simultaneously, and a case in which a state of the first display layer and a state of the second display layer are changed separately; and a light outputting unit that irradiates light to the display medium.
