— Polymer‐stabilized cholesteric‐texture light shutters are made of cholesteric liquid crystal and polymer‐network dispersions. In the polymer‐stabilized cholesteric‐texture reverse‐mode light shutter, the dispersed polymer network stabilizes the transparent planar texture of the liquid crystal at zero field. When an electric field is applied to the dispersion, the liquid crystal is switched to the focal conic texture, which is optically scattering. We systematically studied the effects of the pitch of the liquid crystal on the electro‐optical properties of the light shutters. The dispersion can be used to make projection and reflective displays.
