Anti-ferroelectric liquid crystal with black display in one frame, white in other and ratio giving grey scale

摘要

The present invention provides a spatial light modulator comprising a photoconductor having a current rectifying function and a liquid crystal layer having an antiferroelectric phase as a phase of the liquid crystal located between a pair of transparent electrodes, having a wide viewing angle and high-speed response, capable of reproducing a light-input dynamic picture including half-tone display, and being stable and reliable. Moreover, a liquid crystal display device which can be downsized by comprising a spatial light modulator, comprises a photoconductor having current rectifying function and a liquid crystal layer having the antiferroelectric phase as a phase of the liquid crystal located between a pair of transparent electrodes, a display device to input light to the photoconductor and a power source to apply the driving voltage to the spatial light modulator can be provided.
