摘要： PROBLEM TO BE SOLVED: To change the state of liquid crystal to which a voltage equal to or higher than a second voltage from a transmissive state to a reflecting state while maintaining the part of the reflecting state even when the voltage equal to or higher than a first voltage is applied to the liquid crystal when writing an image to a display medium which displays the image by the reflection and transmission of light by the liquid crystal, and in which the part of the reflecting state and the part of the transmissive state are already present. SOLUTION: When turning the alignment state of cholesteric liquid crystal partially to a planar phase for a display layer having the cholesteric liquid crystal reflecting red light, the part to be turned to the planar phase is irradiated with light while applying the voltage V1 to the entire display layer and the voltage applied to the part to be turned to the planar phase is turned to V2. The applying time of the voltage is equal to or longer than the time needed for transition from a focal-conic phase to the planar phase and is shorter than the time needed for transition from the planar phase to the focal-conic phase.

摘要： PROBLEM TO BE SOLVED: To provide a driving method characterized by a recording medium that, contains a deadband region wider than a light irradiation of a low-light region.
SOLUTION: A voltage exceeding a threshold for the change to a homeotropic orientation is applied to a liquid crystal layer, and synchronously with the voltage application, a display medium is irradiated with light with a first intensity which changes impedance of a photosensitive layer. When the voltage application is stopped, the display medium is irradiated with light which has a second intensity lower than the first intensity and results from not applying a residual voltage exceeding a threshold for the change to a focal-conic orientation for a time longer than a threshold.

摘要： PROBLEM TO BE SOLVED: To change alignment states of each of a plurality of laminated display layers.
SOLUTION: When voltage to be impressed to display layers 7a, 7b in a reset period is larger than VfpbH of Fig.6, both of the display layers 7a, 7b become homeotropic alignment. From that state, a case that the voltage to be impressed to the display layers 7a, 7b in the selection period is smaller than VfpaH and larger than VfpaL of Fig.6 is assumed. In an area to which such voltage is impressed, the display layer 7a with large hysteresis maintains the homeotropic alignment, however, the display layer 7b with small hysteresis becomes focal conic alignment. Meanwhile, when the voltage to be impressed to the display layers 7a, 7b in the selection period is larger than VfpbH of Fig.6, both of the display layers 7a, 7b are still homeotropic alignment. Then, when impression of the voltage is stopped, a homeotropic alignment state shifts to planar alignment.
