    摘要： A display medium is provided. The display medium includes a pair of electrodes disposed so as to have a gap therebetween, an electrolyte disposed between the pair of electrodes, an electroconductive porous layer disposed at least one of the pair of electrodes at the side facing the other electrode, a first electrochromic dye held by the porous layer, a second electrochromic dye dispersed in the electrolyte and forming a color different from the color of the first electrochromic dye. Both the first electrochromic dye and the second electrochromic dye are oxidation dyes which form colors by an electrochemical oxidation reaction and are rendered color-faded by an electrochemical reduction reaction, or reduction dyes which form colors by an electrochemical reduction reaction and are rendered color-faded by an electrochemical reduction reaction. The threshold values of voltages applied to the pair of the electrodes for changing from a color-faded state to a colored state of the first electrochromic dye and the second electrochromic dye satisfy a specific relationship.
