Abstract
PURPOSE: To obtain a electrolytic soln. type WO3 film display element having a long life usable in a wide temp. range by using perchlorate, tetrafluoroborate or hexafluorophosphate of Na or Li as an electrolyte and ethylene glycol diacetate, etc. as a solvent.
CONSTITUTION: A cell provided with display electrode leading portions 4, 7 and display substance layers 3, 6 made of WO3 film on glass substrates 1, 2, respectively is filled with electrolytic soln. 5 consisting of one of LiClO4, NaClO4, LiPF6, NaPF6, LiBF4 and NaBF4 as an electrolyte and ethylene glycol diacetate, ethylcyanoacetate cyclohexanone, succinonitrile, dimethyl (ethyl) maleate, etc. as a solvent.
