    摘要: An optical device and method of manufacturing the same are disclosed herein. In some embodiments, an optical device includes a first outer substrate and a second outer substrate disposed opposite to each other, a liquid crystal element disposed between the first and second outer substrates; and a plurality of adhesive films encapsulating the liquid crystal element, wherein the plurality of adhesive films comprises a curable adhesive film and a non-curable adhesive film. The optical device is capable of varying transmittance and reducing light loss while improving appearance defects. Such an optical device can be used for various applications such as eyewear, for example, sunglasses or augmented reality (AR) or virtual reality (VR) eyewear, an outer wall of a building or a sunroof for a vehicle.

    摘要: A light modulation device is disclosed herein. In some embodiments, a light modulation device includes a first polymer film substrate, a second polymer film substrate, an active liquid crystal layer disposed between the first and second polymer film substrates, wherein the active liquid crystal layer is capable of switching between a vertical orientation state and a twisting orientation state upon application of a voltage, each of the first and second polymer film substrates has an in-plane retardation of 4,000 nm or more for light having a wavelength of 550 nm, a ratio of an elongation (E1) in a first direction to an elongation (E2) in a second direction perpendicular to the first direction of 3 or more, and wherein an angle formed by the first directions of the first and second polymer film substrates is in a range of 0 degrees to 10 degrees.

    摘要: A transmittance-variable film and the use thereof are provided. The transmittance-variable film can be useful in switching between a clear state and a dark state and reducing a difference in contrast ratio between left and right viewing angles, thereby securing excellent bilateral symmetry. Such a transmittance-variable film can be applied to various applications including various materials for buildings or vehicles requiring the control of transmissivity, or eyewear such as goggles for sports or experiencing augmented realities, sunglasses, helmets, etc.
