Abstract

A method for forming an electrochromic layer pattern includes forming a transparent electrode layer and a photoresist layer on a transparent substrate, forming a photoresist pattern by laser interference lithography, and depositing an electrochromic layer pattern on the transparent electrode through openings defined by the photoresist pattern by depositing an electrochromic layer on a front surface of the substrate and then lifting up the photoresist pattern. An insulation layer may be further formed between the transparent layer and the photoresist layer. Here, the electrochromic layer may be formed after an insulation layer pattern is formed using the photoresist pattern as an etching mask. In this case, the electrochromic layer pattern is formed in openings defined by the insulation layer pattern. As a result, a contact surface area between the electrochromic layer pattern and the ion conductive layer is increased to ensure a rapid response speed.

Description

technical field

[0001] The present invention relates to a method for preparing an electrochromic device, and more particularly to a method for forming an electrochromic layer pattern of an electrochromic device, a method for preparing an electrochromic device using the above method, and an electrochromic device with an electrochromic layer pattern. Color changing device. Background technique

[0002] An electrochromic device (ECD) is a color display device using an electrochromic material that is colored or decolorized by electrochemical oxidation or reduction depending on the direction in which an electric current is applied. The electrochromic operating methods are divided into cathodic and anodic operating methods. The cathodic electrochromic material forms color when reduced at an electrode composed of the negative pole, while the anodic coloring point to the color changing material either at the anode or at the positive pole. Additionally, if the direction of the curr...
