    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 first orientation state and a second orientation state when a voltage is applied, and a polarizer, wherein each of the first and second polymer film substrates have 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 reflectance-variable mirror using a liquid crystal cell is disclosed herein. In an embodiment, the reflectance-variable mirror may comprise a first liquid crystal cell including a guest host liquid crystal layer, a first reflective polarizing film, a second liquid crystal cell including a retardation-variable liquid crystal layer, a second reflective polarizing film and an absorbing plate sequentially. The reflectance-variable mirror can realize excellent reflectance-variable characteristics by lowering the reflectance in an antireflection mode.

    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, a reflective layer, wherein the active liquid crystal layer is capable of switching between a first orientation state and a second orientation state different from the first orientation state upon application of a voltage, each of the 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： The present application relates to a method of manufacturing an optical device, an optical device and a use of the optical device. The method of manufacturing an optical device of the present application can form a patterned mold layer to maintain an appropriate gap between the upper and lower substrates, and can apply an imprinting process in patterning the mold layer to simply manufacture the mold pattern having the desired shape. In addition, the optical device manufactured by the above manufacturing method can have a low driving voltage and no short circuit phenomenon, and be realized as a flexible device. Such an optical device can be applied to various display devices such as LCDs.
