Display element and production thereof
First Claim
1. A display element which comprises a coloring substance, which separates out, dissolves, or changes in color upon electrochemical reduction or oxidation, and a polymeric electrolyte, which are both held between a first electrode and a second electrode, said polymeric electrolyte being formed from a monomer or an uncrosslinked polymer as a starting material by polymerization or crosslinking between said first and second electrodes.

Abstract
A high-quality-easy-to-fabricate display element and a process for production thereof. The display element (18) has between transparent pixel electrodes (2) and a common electrode (6) a polymeric electrolyte (5) which contains a coloring substance (metal ions) such as AgI which separates out, dissolves, or changes in color upon electrochemical reduction or oxidation. The process includes placing a monomer or an uncrosslinked polymer of a solution (5A) as a starting material for the polymeric electrolyte layer (5), together with the coloring substance (metal ions) and a supporting electrolyte, between the transparent pixel electrodes (2) and the common electrode (6) and polymerizing or crosslinking the starting material by thermal polymerization or the like, thereby forming the polymeric electrolyte layer (5).
