More Information
Summary:Disclosed is an electrochromic display element, including a display substrate, a display electrode, an electrochromic layer, an opposed electrode, and an opposed substrate, wherein the electrochromic layer is formed on the display electrode, a liquid crystal composition that includes a low-molecular liquid crystal and an ionic liquid is present between the display electrode and the opposed electrode, and the ionic liquid includes a tetracyanoboric acid ion and/or tris(pentafluoroethyl)trifluorophosphoric acid ion as an anionic component.
