Abstract
PURPOSE: To provide the titled apparatus which has a long life, high display quality level and a high contrast ratio, by a method wherein a nonaqueous electrolyte incorporated with a styryl-analogous compd. and a supporting electrolyte is enclosed between a transparent base plate having a transparent electrode and a colored base plate having a transparent electrode.
CONSTITUTION: A nonaqueous electrolyte incorporated with a supporting electrolyte and a styryl-analogous compd. of the formula (wherein Q is a benzene ring with or without substituents and/or condensed rings; R1, R2 are each lower alkyl, hydroxyalkyl, alkoxyalkyl; R3 is H, alkyl, alkoxy, halogenonitrile, arom. group, phenoxy; Y is O, S; Z is a 2W4C alkylene with or without an alkyl-substd. group which is necessary for forming a cyclic structure together with -N-C-Y; A is a condensation reaction residue of an arom. or heterocyclic aldehyde, or an arom. or heterocyclic nitroso compd.) is enclosed in a space formed between a transparent base plate having a transparent electrode and a colored base plate having a transparent electrode.
