摘要： A method of manufacturing a light modulation device is disclosed herein. In some embodiments, a method comprises transferring a first substrate between a first unwind roll and a take-up roll, wherein an adhesive layer is disposed on the a first surface of the first substrate, transferring a second substrate between a second unwind roll and the take-up roll, wherein the second substrate includes a spacer and a liquid crystal alignment film formed on a first surface of the second substrate during the transfer and prior to an attachment with the adhesive layer of the first substrate, and attaching the first and second substrates via respective first surfaces thereof by passing the first and second substrates through an opening between adjacent attachment rolls to form a light modulation device.

摘要： An optical device includes a first outer substrate; a second outer substrate disposed opposite to the first outer substrate; and an active liquid crystal film or a polarizer, wherein the active liquid crystal film or the polarizer is encapsulated by an encapsulating agent between the first and second outer substrates and wherein a shrinkable film adjacent to any one of the first and second outer substrates is further included. The optical device is capable of varying transmittance. The optical device can be used for various applications such as an eyewear, for example, sunglasses or AR (augmented reality) or VR (virtual reality) eyewears, an outer wall of a building or a sunroof for a vehicle.
