| 摘要 |
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 ( 5 A) 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 ).
