A matrix driving method for a liquid crystal display which has liquid crystal which exhibits a cholesteric phase and is capable of keeping an image displayed thereon after turn-off of an electric field applied thereto by using a plurality of scan electrodes and a plurality of data electrodes which are arranged to face and cross each other with the liquid crystal in-between. The method has a reset step of applying a reset pulse to reset the liquid crystal to a homeotropic state, a selection step of selecting the final state of the liquid crystal, and an evolution step of stabilizing the liquid crystal to the selected state. The selection step has a first step including a time of applying substantially 0 volt to the liquid crystal, a second step of applying a selection pulse to select the final state of the liquid crystal and a third step, after the second step, including a time of applying substantially 0 volt to the liquid crystal. In at least either the first step or the second step, a compensation pulse may be applied to the liquid crystal. The form of the compensation pulse is determined depending on temperature or is determined so that a plurality of liquid crystal layers will have the same scanning speed.
