Abstract

PURPOSE: To enhance the reliability of a display cell without any change in responsiveness for a long period of time by providing the 2nd electrochromic coloring layer colored to such a range at which the electromotive force geneated assumes a fixed value, on a counter side electrode.
CONSTITUTION: Display side electrodes 2 comprising transparent conductive films of desired patterns are formed on a light transmittable display side substrate 1, and the 1st electrochromic coloring layer 3 is formed in the display positios of the electrodes 2. A transparent insulation film 4 is coated on the lead parts. In addition, a counter side electrode 6 is formed over the entire surface on a back side substrate 5, and the 2nd electrochromic coloring layer 7 which is so colored that the value of x is in the region of the formula when the coloring state of WO3 is expressed as LixWO3 by using WO3 and using an Li ion conductor as electrolyte is provided on said electrode 6, and a porous layer 9 made of white alumina ceramics is inserted on this coloring layer 7. Both substrates 1, 5 are spaced by means of a spacer 8, and the outside circumference of the spacer 8 is fixed by silicone rubber 11, thence an LiClO4 soln. is sealed into a gap 10.
