Abstract

PURPOSE: To provide an electrochromic display element containing a specific novel electrochromic material, leaving little or no color when erased, having high color density, and capable of accepting various kinds of solvents and developing the color over a wide voltage range.
CONSTITUTION: The objective display element contains the electrochromic liquid obtained by dissolving (A) a quaternary ammonium salt of formula [R1, R2, R3 and R4 are H, alkyl, alcoxy, (substituted) phenyl, benzyl, naphthyl, anthryl or heterocyclic group; X- is anion] (e.g. phenyltrimethylammonium chloride) and optionally (B) a supporting electrolyte (e.g. LiClO4, etc.), in (C) an aprotic polar solvent such as water, alcohol, DMF, etc.
