摘要： A liquid crystal device, comprises: a pair of opposite electrodes and a ferroelectric liquid crystal showing a first and a second alignment state depending on the direction of an electric field applied thereto and disposed between the opposite electrodes. The ferroelectric liquid crystal is placed in a stated of causing a relaxation such that, when a voltage pulse equal to the threshold is applied between the opposite electrodes, the ferroelectric liquid crystal causes a change in its molecular alignment state from one molecular alignment state toward the other molecular alignment state and continues the change in its molecular alignment state even after the removal of the voltage pulse until the change reaches a saturation in a certain period.
