Abstract

PURPOSE: To obtain the element of good contrast which is capable of making multicolor displaying by combining the electrochromic (EC) electrodes which color in an oxidated state, the EC electrodes which color in a reduced state and the 3rd electrodes.
CONSTITUTION: The 1st glass substrate 1 provided with a transparent electrode layer 2 and the layer 4 of metal oxides which color in an oxidated state (e.g., V2O3, WO2, Cu2O), the 2nd glass substrate 1" provided with a transparent electrode layer 2"' and the layer 5 of metal oxides which color in a reduced state (e.g., V2O5, WO3, GaO) and the 3rd glass substrate 1' provided with transparent electrode layers 2', 2" on both surfaces are used. Namely, the 3rd glass substrate 1' is disposed between the opposed 1st, 2nd glass substrates 1, 1" and electrolyte (e.g., propylene carbonate solution containing LiClO4) is filled between the respective substrates, whereby the electro-coloring display element is provided.
