The present application relates to a liquid crystal cell and a use of the liquid crystal cell. The present application can provide a liquid crystal cell which is capable of switching between a transparent mode and a scattering mode by using a non-ionic compound as a liquid crystal additive for realizing the EHDI characteristics and has excellent performance such as a driving voltage characteristic, a haze characteristic and reliability by securing solubility of the additive for liquid crystals. Such a liquid crystal cell can be applied to various light modulation devices such as a smart window, a window protective film, a flexible display device, a light shielding plate for transparent display, an active retarder for 3D image display, or a viewing angle adjusting film.
