Abstract

PURPOSE: To protect an electrode terminal from an electrolyte and to enlarge a lower electrode thereby to improve the resposiveness and lifetime by forming an electrochromic color developing layer on the electrode of an insulating protecting layer, which is formed in the periphery of the electrode, and a display portion.
CONSTITUTION: An opposite electrode and a display electrode 18 are placed at a preset spacing inbetween, and an electrolyte is arranged inbetween. The electrode 18 has its periphery covered with an insulating protecting layer 20, and an electrochromic color developing layer 19 is laminted thereabove upon the display portion of the electrode 18 and upon the peripheral layer 20. In this instance, the length b of the layer 19 on the layer 20 is made to range in an x axis within the Equation (wherein: a stands for the thickness of the layer 19, D stands for the diffusion coefficient of electrons in the layer 19; τ stands for the following time of 0.0625 seconds of human eyes to the change in the outside light; and A stands for the density discriminating capacity of 0.95 of human eyes).
