Abstract

Provided are a liquid crystal device, a composition capable of forming a liquid crystal layer, a method of manufacturing the liquid crystal device, a system for manufacturing the liquid crystal device, and a use of the liquid crystal device. The liquid crystal device is a device capable of exhibiting, for example, a normally white or black mode, which may exhibit a high contrast ratio and be driven with a low driving voltage, and exhibit excellent durability such as thermal stability. Such a liquid crystal device may be applied to various optical modulators such as a smart window, a window protective film, a flexible display device, an active retarder for displaying 3D images, or a viewing angle control film.
