摘要：
In a ferroelectric liquid crystal element, in order to excite a reverse electric field within the element in response to a waveform of a non-rewriting voltage, properties of the ferroelectric liquid crystal material, an element structure, driving waveforms, or other factors are adjusted so that molecules of the ferroelectric liquid crystal are allowed to switch between bistable states in response to a waveform of a rewriting voltage, while the ferroelectric liquid crystal exerts an anti-memory phenomenon in response to a waveform of a non-rewriting voltage.
