发明名称 Optical modulation element.
摘要 <p>An optical modulation element includes a polarizer, a modulator, and an analyzer, wherein each of the polarizer, the modulator, and the analyzer has a chiral smectic liquid crystal which has substantially the same temperature dependency of a tilt angle, the polarizer and the analyzer are arranged so that molecular axes of the chiral smectic liquid crystal of the polarizer and the analyzer cross each other, and the chiral smectic liquid crystal of the modulator exhibits at least two stable arrangement states, and the modulator is arranged so that a molecular axis of one of the two stable arrangement states is substantially parallel to the molecular axis of one of the polarizer and the analyzer. &lt;IMAGE&gt;</p>
