Abstract
One embodiment provides a flexible smart window which includes an electrochromic structure including a discoloration layer, a first polyimide film disposed on the electrochromic structure, a second polyimide film disposed under the electrochromic structure, and a first adhesion promoting layer disposed on the first polyimide film and including at least one selected from the group consisting of a metal oxide, a metalloid oxide and an organic silane compound. Structural stability of the flexible smart window may be enhanced by improving an adhesive force between the polyimide film and the electrochromic structure in a high temperature process.
