Abstract
(EN) Provided are an electrochemical display element that has excellent driving stability and durability, and a manufacturing method therefor. The disclosed display element contains at least one pair of counter electrodes and a compound that is disposed in between the pair of electrodes and undergoes coloration, decoloration, or discoloration via an electrochemical reaction on the surface of at least one of the electrodes. The display element is characterized in that a compound having a charge imbalance in the molecular structure is included between the counter electrodes and in that the work function φ'(V) of the electrodes with the compound having the charge imbalance in the molecular structure adsorbed thereto, and the oxidation-reduction potential Va(V) at which the compound undergoes coloration, decoloration, or discoloration satisfy the relationship represented by formula (1). Formula (1): |φ' − Va| ≤ 1.8
(FR) L'invention concerne un élément d'affichage électrochimique qui possède une excellente stabilité d'actionnement et une excellente durabilité, ainsi qu'un procédé de fabrication de celui-ci. Cet élément d'affichage comprend au moins une paire de contre-électrodes et un composé qui est disposé entre la paire d'électrodes et est soumis à une coloration, une décoloration ou une altération de couleur par le biais d'une réaction électrochimique sur la surface d'au moins une des électrodes. L'élément d'affichage est caractérisé en ce qu'un composant ayant un déséquilibre de charge dans la structure moléculaire est inclus entre les contre-électrodes, et en ce que la fonction de travail φ'(V) des électrodes sur lesquelles est adsorbé le composé ayant un déséquilibre de charge dans la structure moléculaire, et le potentiel d'oxydation-réduction Va(V) auquel le composé est soumis à une coloration, une décoloration ou une altération de couleur, respectent la relation exprimée par la formule (1) : |φ' − Va| ≤ 1,8.
