Abstract

PURPOSE: To achieve the improvement of driving characteristics and the reduction of coloring density fluctuations by specifying the sealing method of the cell injection hole of electrolyte.
CONSTITUTION: The electrolyte injection hole 8 of a second substrate 4 formed with a transparent conductive film 6 and EC material 7 above a glass made first substrate 1 formed with a transparent conductive film 2 and EC material 3 of desired electrode patterns is sealed with a metal having an oxidation-reduction potential more basic than the oxidation-reduction potential of the EC materials 3, 7 for electrolyte such as indium or other after injection of the electrolyte 9 to electrically shortcircuit the sealing metal 10 and the EC material 3 acting as a counter electrode through the transparent conductive film 2. This causes a kind of a battery wherein the sealing material 10 and EC material 3 act as both electrodes to be formed through the electrolyte 9, thus letting the device be maintained automatically at a fixed potential even at the driving stoppage of the voltage between the EC material 3 and electrolyte 9 and letting the intended object by achieved.
