ABSTRACT:
An image writing/display device has a voltage applying section, a pressure applying section, an initialization controlling section, and an image writing controlling section. In a state in which a display medium having a pair of electrodes and a display layer that is sandwiched between the pair of electrodes and whose reflectance is changed is positioned, the voltage applying section applies voltage to the pair of electrodes for changing the reflectance of the display layer. The pressure applying section applies pressure for changing the reflectance of the display layer. The initialization controlling section makes the display layer a uniform reflectance by applying pressure to the display layer with the pressure applying section. The image writing controlling section writes an image by applying data voltage from the voltage applying section to specific regions, that correspond to image data, of the display layer between the pair of electrodes.
