PROBLEM TO BE SOLVED: To provide an electrochromic display element having excellent light fastness in reflective display and transmissive display and excellent coloring and decoloring characteristics without an increase in a voltage required for coloring and decoloring.SOLUTION: The electrochromic display element comprises a display substrate, a display electrode, an electrochromic layer disposed in contact with the display electrode, a counter substrate disposed to face the display substrate, a counter electrode, a charge holding layer disposed in contact with the counter electrode, and an electrolyte layer filling a space between the display substrate and the counter substrate. A metal hydroxide is dispersed on surfaces of titanium oxide particles and in the titanium oxide particles included in the electrochromic layer. |
