Abstract
PURPOSE: To increase the coloring and decoloring reaction speeds of an electrochromic (EC) layer and enhance the response properties of an EC display cell by adding a mixture of an org. solvent and an alkali salt and a specified amount of water to an electrolyte in the cell.
CONSTITUTION: Transparent electrode 2 having a display pattern and a lead portion is formed on the inside of display side substrate 1, and WO3 layer 3 is formed as an EC layer on film 2 corresponding to the pattern. SiO2 insulating film 4 is vacuum-deposited on the lead portion, and opposite electrode 6 is formed on backside substrate 5. They are then sealed with a spacer such as a glass thin wire in- between. An alkali salt such as LiClO4 is dissolved in an org. solvent for a nonaqueous electrolyte such as propylene carbonate, and water is added to the soln. in an amount equal to the total amount of the maximum coordination number for the cation of the salt to prepare electrolyte soln. 7, which is filled in the resulting EC cell. Thus, ion such as H+ having a small ionic radius and a high diffusion speed is implanted in layer 3, so quick coloring and decoloring can be accomplished.
