The present invention relates to a liquid crystal display device that includes a particular color filter containing a material containing chiral liquid crystals and a particular pigment. The present invention provides a liquid crystal display device that can prevent a decrease in the voltage holding ratio (VHR) of a liquid crystal layer and solve the problem of display defects, such as white spots, variations in alignment, and burn-in.

Provided are a liquid crystal cell and a use thereof. An exemplary liquid crystal cell can be implemented in a bistable mode switching between a haze mode and a non-haze mode even with low driving voltage. Such a liquid crystal cell can be applied to various optical modulation apparatus, such as a smart window, a window protection film, a flexible display element, an active retarder for a 3D visual display, and a viewing angle-controlling film.
