Abstract
There is provided a display element which is constituted of simple members, can achieve low-voltage drive and exhibits high display contrast and superior response speed. The display element comprises opposed electrodes having therebetween an electrolyte layer containing silver or a silver-containing compound, wherein the opposed electrodes are driven so that silver is dissolved and deposited and the electrolyte layer further contains at least one compound selected from the group consisting of compounds represented by formula (1), (2) or (3).
Claims7
A display element comprising opposed electrodes having therebetween an electrolyte layer containing silver or a compound containing silver in a chemical structure, wherein the opposed electrodes are driven so that silver is dissolved and deposited and the electrolyte layer further contains at least one compound selected from the group consisting of compounds represented by formula (1), (2) or (3):
- wherein Q1 is an atomic group necessary to form a 5- or 6-membered cationic aromatic ring with a nitrogen atom, R1 is a substituted or unsubstituted alkyl group or a substituted or unsubstituted alkenyl group, and X− is an anion,
- wherein A1 is a nitrogen atom or a phosphorus atom, R2 to R5 are, each independently a substituted or unsubstituted alkyl group or a substituted or unsubstituted alkenyl group, and X− is an anion;
- wherein R6 to R11 are each independently a substituted or unsubstituted alkyl group or a substituted or unsubstituted alkenyl group, and X− is an anion.
