Abstract
PURPOSE: To obtain the electrochromic display device (ECD) which uses inexpensive metals (Al, Cu, etc.) and is nevertheless wider in service temperature range and is long in life by using the back substrate composed of a metal plate having resin covering as a cell case.
CONSTITUTION: In the ECD formed by sealing a light scattering plate 6 and electrolyte 10 by way of a spacer 7 between the transparent substrate 1 provided with transparent conductive films 2 and ECD material layer (WO3 film) 3 and a back substrate 4; the back substrate 4 formed by applying lamination coating by resins (polyethylene, polypropylene, etc.) 20 on a metal plate of Al, Cu, Ni, stainless steel, etc. is used to form the cell case. The electrolyte injection port 8 of the aforementioned cell case is provided at the metal portion having resin covering and this is sealed by the same resin used for the covering after the injection of an electrolyte, whereby the liquid leakage may be prevented and the cell made longer in life and higher in reliability.
