Electrochromic display element and display device

Abstract

Disclosed is an electrochromic display element, including a display substrate, an opposed substrate that is opposed to the display substrate, an opposed electrode being formed at a display-substrate-opposed side of the opposed substrate, a first display electrode and a first electrochromic layer being laminated at an opposed-substrate-opposed side of the display substrate, a single porous film being formed between the display substrate and the opposed substrate, a second display electrode and a second electrochromic layer being laminated at a display-substrate-opposed side of the porous film, a third display electrode and a third electrochromic layer being laminated at an opposed-substrate-opposed side of the porous film, and an electrolyte being present between the display substrate and the opposed substrate.

Dependencies are inferred from the claim text.
