    Abstract: 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.

    Abstract: 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.

    Abstract: A method for manufacturing an optical device and an optical device is provided. The manufacturing method is capable of minimizing or eliminating dotting unevenness that may occur when an optical device is manufactured by a dotting process. In particular, even when a large cell gap is present or a polymer substrate is applied as a substrate so that high-temperature heat treatment is impossible, such method of the present application can provide an alignment film having improved orientation by improving the dotting unevenness.
