Abstract

There is provided an electrochromic display that includes a display substrate, which includes a display electrode on a first substrate and an insulating film on or above the display electrode; a counter substrate having a counter electrode on a second substrate, the counter substrate facing the display substrate; and a color-developing layer containing an electrochromic material disposed in a region surrounded by a sealing member between the display substrate and the counter substrate. The insulating film is disposed on or above the display electrode except for a display region of the display electrode in the region surrounded by the sealing member.

Claims5

Dependent claims

An electrochromic display, comprising:

a display substrate, which includes at least one display electrode on a first substrate and an insulating film;
a counter substrate having a counter electrode on a second substrate, the counter electrode facing the at least one display electrode with the insulating film disposed on at least a portion of the at least one display electrode;
and
a color-developing layer containing an electrochromic material disposed in a region surrounded by a sealing member between the display substrate and the counter substrate,
wherein the insulating film has a predetermined shape such that a region where the insulating film is disposed is a non-display region of the at least one display electrode, and a region surrounded by the sealing member where the insulating film is not disposed is a display region of the at least one display electrode.
