PURPOSE:To form an element having excellent responsiveness and is free from deterioration with age in an electrochromic (EC) display element using a liquid electrolyte, by using the liquid electrolyte in the solidified state in which the electrolyte is absorbed in a specific cross-linked type polymer. CONSTITUTION:A solidified electrolyte obtd. by adsorbing a liquid electrolyte on a cross-linked polymer obtd. by cross-linking PVA with a dicarboxylic acid (anhydride) (preferably the polymer crosslinked by using about >=2wt% pyromellitic anhydride) is used. The above-mentioned solidified electrolyte 4 is sandwiched between an upper glass substrate 1 provided with a transparent conductive film 2 of tin oxide, etc. and EC electrodes 3 consisting of a thin film of Prussian blue, etc., and a lower glass substrate 7 provided with a counter electrode 6 of Cr-Au, etc., whereby the EC display element is formed (a symbol 5 is a spacer). |
