Beschreibung
Zusammenfassung:	An optical device is disclose herein. In some embodiments, an optical device includes an active liquid crystal element film, wherein the active liquid crystal element film comprises two base films, an active liquid crystal layer present between the two base films, wherein the active liquid crystal layer contains a liquid crystal compound and is capable of switching between a first oriented state and a second oriented state, and a polarizing coating layer, wherein the polarizing coating layer is present between one of the two base films and the active liquid crystal layer. The optical device is capable of varying transmittance, and can be used for various applications such as sunglasses, AR (augmented reality) or VR (virtual reality) eyewear, an outer wall of a building or a sunroof for a vehicle.
