PROBLEM TO BE SOLVED: To provide an electrochromic display device capable of having high display performance in a simple configuration. SOLUTION: The electrochromic display device 100 includes a first substrate 10, first electrodes 20..., a second substrate 30, second electrodes 40... and an electrochromic composition layer 50, with pixels 60 formed in a region where the first electrodes 20... and the second electrodes 40... three-dimensionally intersect, wherein the electrochromic composition layer 50 is configured to include a porous material 51 having pores 51a... that penetrate in an approximately vertical direction with respect to the first substrate 10 and the second substrate 30 and that are smaller in size than the pixels 60, and an electrochromic composition 52 introduced into the pores 51a... of the porous material 51, and wherein the electrochromic composition 52 develops a color on the interface between the electrochromic composition layer 50 and the second electrode 40 when a current is applied between the first electrode 20... and the second electrode 40....
