Title ELECTROCHROMIC RENDERING/DISPLAYING DEVICE NEW_EN
Abstract The present invention is provided with: a substrate 10; a lower conductive film 12 disposed on the substrate; an electrochromic material 14 and an electrolyte 16 disposed on the lower conductive film; an upper transparent conductive film 24, disposed on the electrochromic material and the electrolyte, with an insulating spacer 22 interposed therebetween; a transparent film 26 disposed on the upper transparent conductive film; and a means (28) for applying a voltage between the lower transparent conductive film and the upper transparent conductive film, wherein when the transparent film is pressed from the upper surface thereof, the transparent film is bent, a gap formed by the spacer disappears, the upper transparent conductive film is brought into electrical contact with the electrochromic material or the electrolyte thereunder so as to locally pass an electrical current, an electric field is applied only to a portion, of the electrochromic material, directly under the contact point, and thereby, a local color of the electrochromic material is changed. Accordingly, the electrochromic rendering/displaying device which allows a local color change (coloring, decoloring, discoloring) by means of a simple structure is provided.
