摘要：
The present invention provides a display medium which prevents a decrease in reflectance during storage at high temperatures, and a writing apparatus using the display medium. A photoconductive layer 24, a selective light transmission layer 22, and a liquid crystal layer 20 are laminated between substrates 12 and 14, which have electrodes 16 and 18, respectively, to form a display medium 10. The selective light transmission layer 22 as a color layer is composed of a deionized material. The ion concentration of the selective light transmission layer 22 is controlled to be within a predetermined range.
