Abstract

PURPOSE: To prolong drive life without detracting a display unit from its response property by providing an electrolyte between a display electrode substrate, having an electrochromic substance layer consisting of two kind of layers differing in density, and an opposite electrode substrate arranged opposingly.
CONSTITUTION: In manufacture of the electrochromic display unit consisting of transparent glass substrate 21, transparent conductive film 22, glass substrate 25 and transparent conductive film 26, layer 23a of ≥95% in density and about 0.1μm in film thickness is formed, by WO3-ion-plating, etc., on transparent conductive film 22 formed by vapor-depositing In2O3. Next, WO3 is vapor-deposited by electron beams to form layer 23b of 20W85% in density and about 0.4μ. Then, the 2nd layer 23b is positioned in contact with electrolyte 28 made of γ-butyrolactone, LiClO4, etc.
