With a view to development of optically addressed spatial light modulators with high resolution for high-brightness projection displays, a morphological design and its fabrication have been carried out for polymer-dispersed liquid crystals. To finely disperse the small and uniform-size liquid crystal droplets, polymer-dispersed liquid crystals were produced with different liquid crystal content, ultraviolet light intensity, and substrate wetness. The polymer morphology of the interior and the interface with the substrate were observed with a scanning electron microscope. Based on the experimental results, transmission-type spatial light modulators were fabricated with polymer-dispersed liquid crystals (10 μm thick) and Bi12SiO20 photoconductor (250 μm thick). By inputting fine optical images, the limiting resolution of the device was measured. The resolution of the spatial light modulator strongly depends on the dispersive structures of the liquid crystal microdroplets and reaches a maximum of 64 line pairs/mm as a result of optimization.
