The electrochromic material is generally classified into a stencil material and an inorganic material, and an inorganic material is preferable for stability, such as tungsten oxide or titanium oxide. Moreover, conventionally, electrochromic devices use glass as a substrate, and when used in practice, they are often limited by the material of the substrate and cannot be bent at any time, and their use is limited. In addition, conventional electrochromic devices cannot be fabricated using roll to roll, making it relatively impossible to provide a low cost electrochromic device. U.S. Patent No. 6,193,379 discloses an electrochromic device primarily for use in a rearview mirror. Referring to FIG. 1, the electrochromic device comprises a month having a front surface 1〇〇a and a rear surface 1〇〇b!

The electrochromic material may be an inorganic metal oxide or an organic material. Yes, The electrochromic material of the electrochromic device of this patent is blended with the electrolyte for conducting ions, so it must be continuously subjected to a relatively high voltage to maintain the discoloration state, and the coloring memory cannot be obtained. 〇i〇r memory effect). In addition, since the electrochromic material is dissolved

105 t , = high knife material that is still exposed to organic solvents and still retains its properties and contains aliphatic hydrocarbons. However, this patent does not mention or teach that the substrate is flexible. In addition, the electrochromic material contained in the cavity is in the form of a solution. When the entire device is bent, the electrolysis may be caused. The color change material is exposed, which also affects the range of post-reading applications.
