Abstract:
A display element containing an electrolyte (containing a metal salt compound) disposed between counter electrodes, wherein a compound represented by the following Formula (A) is immobilized on at least one of the counter electrodes: wherein R22 represents an aryl group, R23 and R24 independently represents a hydrogen atom or a substituent; X represents >N—R25, an oxygen atom or sulfur atom; and R25 represents a hydrogen atom or a substituent, a ratio of a region on which the compound of Formula (A) is immobilized to a region on which the compound is not immobilized is 1:4 to 4:1. A black display, a white display and a color display having a color other than black are achieved by the operation of the counter electrodes.
