The present application relates to light modulation devices and uses thereof. The light modulation device includes an active liquid crystal film layer having a first polymer film substrate and a second polymer film substrate arranged to face each other; An active liquid crystal layer between two polymer film substrates and containing a liquid crystal host and a dichroic dye guest. The present application can provide a light modulation device having both excellent optical and mechanical properties by using a polymer film also having optical anisotropy and mechanical anisotropy as a substrate. |
