Abstract

PURPOSE: An electrochromic (EC) display element which can provide a stable, clear, yellow-green display with a good contrast, obtained by employing a specific organic redox compound.
CONSTITUTION: In an EC display element (each symbol 3 means a lead wire connecting a terminal 8 with electrodes) formed by disposing, in an opposed position, a transparent base 1 provided with transparent electrodes 2 and a base 5 provided with an electrode 4, sealing the peripheries with seals 6 and sealing a solution 7 of a redox compound in a cell formed between both the bases, there is employed as said redox compound, a compound (oligomer) represented by the formula, wherein R is alkylene or dialkylphenylene, X- is a monovalent anion and n is an integer (preferably about 2W10).
