Paper Abstract

We propose a chiral-nematic liquid crystal (CN-LC) device that reflects the infrared light, where the planar state is transparent over the entire visible wavelengths and the focal conic state scatters the light achromatically. The proposed CN-LC device can be operated at a low voltage because of the long pitch. A liquid crystal display (LCD) switchable between reflective and transmissive modes can be realized by stacking a CN-LC layer and a nematic LC layer.
