Abstract

PURPOSE: To decrease power consumption and make display color sharp by sealing the electrolyte contg. iodine ions mixed with starch sugar into a cell case provided with display electrodes and a common electrode on the inside surface.
CONSTITUTION: A transparent insulation substrate 1 formed with display electrodes 4 on the inside surface and an insulation substrate 2 formed with a common electrode 5 on the inside surface are bonded and superposed by way of a sealing material 3 in the state that a thick opaque porous plate 6 is interposed between the electrodes 4 and the electrode 5, whereby a cell case A is formed. The electrolyte 7 prepared by mixing 1W10wt% starch 8 to a soln. prepared by dissolving an iodine compound such as KI or NaI into water or org. solvent is sealed into this case A. If the voltage higher than the reference voltage to be applied to the electrode 5 is applied to the electrodes 4, the iodine ions in the electrolyte 7 are attracted to the electrodes 4 and become iodine molecules. These iodine molecules cause the starch 8 on the electrode 4 surface to form a sharp bluish purple color.
