Zusammenfassung: | A adjustable heat insulation window is provided with a first transparent substrate, a second transparent substrate, and a heat insulation layer disposed between the first transparent substrate and the second transparent substrate. The heat insulation layer is provided with a liquid crystal composition having a plurality of liquid crystal molecules, a dichroic dye, and an ionic salt. The liquid crystal molecules have negative anisotropies, and the dichroic dye has a visible absorption wavelength ranged from 400 to 780 nm. |
