Abstract

PURPOSE: To eliminate defects such as liquid leakage, the evolution of gas ghrough electrolysis and corrosion of WO3 film and achieve longer life by solidifying an EC layer by the use of WO3 as electrochromic (EC) material and LiI as an alkali ion source.
CONSTITUTION: EC material 3 such as WO3 is formed on the transparent electrode 2 of a glass substrate 1 and a LiI film 4 is provided thereon. Further it is coated thereon with a silicon oxide film 5 and is provided with an electrode 6 of Al or the like on the film 5. If its electrode 6 side is made + by DC voltage and the substrate 1 side-, this EC element causes coloring in a blue color and if the voltage is made opposite, it is decolored. In this way, the display element of a long life and low power consumption using the solid EC material of good coloring characteristic is obtained.
