We developed a dual mode reflective cholesteric display which works in the traditional bistable mode as well as in a monostable mode. In the bistable mode, it is operated between the reflecting planar state and non‐reflecting focal conic state, both of which are stable at zero voltage. The bistable mode is suitable to display static images. In the monostable mode, it is operated on all the intermediate states between the planar and focal conic states. It is fast and has low driving voltage, and can exhibit gray levels of reflectance determined by the applied voltage. The monostable mode is suitable to display video rate dynamic images.
