ABSTRACT:
A spatial light modulator has a photoconductive layer deposited on one glass substrate having a transparent electrode. A first liquid crystal alignment film is formed on the photoconductive layer. A second liquid crystal alignment film is formed on another glass substrate having another transparent electrode. A ferroelectric liquid crystal is filled between the first and second liquid crystal alignment films.
