Abstract

PURPOSE: To increase the contact area of counter electrode reaction material and electrolyte and obtain the electrochromic display device of good characteristics by placing the counter electrode reaction material as powder at the periphery of the counter electrode current collector and so constructing the device that it does not make contact with display electrodes.
CONSTITUTION: A spacer 9 and porous plate (alumina sintered plate) 17 are disposed on the glass plate provided with transparent electrodes 2 and display electrode material (WO3, etc.) 3. The glass plate 1 and spacer 9 as well as the spacer 9 and porous plate 17 are bonded. Next, the carbon powder of mean grain size about 10μ which has been kneaded to paste form by electrolyte 8 is coated as counter electrode reaction material 14 on the back surface of the porous plate 17 and the glass plate 6 provided with current collector (platinum vapor-deposition film) 5 is bonded to the spacer 9, after which the electrolyte injection hole 12 reaching the porous plate 17 through the spacer 9 is formed and the electrolyte 8 is injected through this hole 12 and the hole is sealed, whereby the display device is provided.
