Abstract

PURPOSE: To suppress reduction reaction in display electrodes and achieve the improvement in cycle life by providing a metal oxide layer between the display electrodes and electrochromic layer.
CONSTITUTION: Segment electrodes 2 are deposited on a front glass substrate 1 and an oxide film 4 such as SiO2 is formed on the exposure surface of the substrate except the electrodes 2. Next, a metal oxide layer 9 such as TiO2 is formed to about 1000Å thick on the electrodes 2 and film 4, after which an electrochromic layer 3 such as of WO3 is provided on the positions corresponding to the electrodes 2. A common electrode 6 opposing to the electrodes 2 is provided on a glass substrate 7 which becomes a back substrate. The substrates 1, 7 are fixed by maintaining a fixed spacing by a spacer 5 and electrolyte is injected, whereby an electrolyte layer 8 is formed.
