LIGHT CONTROL ELEMENT, LIGHT CONTROL SHEET, INTERMEDIATE FILM FOR LAMINATED GLASS, AND LAMINATED GLASS

摘要

Provided are a light control element and a light control sheet, in which the time from voltage application to the completion of the change in light transmittance is extremely short. Also provided are an intermediate film for laminated glass, said film being made using the light control sheet, and laminated glass having the intermediate film. The disclosed light control element includes: a pair of transparent plates, each having a conductive film; and an anode electrochromic layer containing a conductive polymer, an electrolyte layer, and a cathode electrochromic layer containing a mixed-valence complex, the layers being laminated sequentially between the transparent plates.
