Abstract: A reflective type liquid crystal optically addressed spatial light modulator has a first transparent substrate(1b), a first transparent electrode (2b) formed on the first transparent substrate (1b), and a photosensitive layer (3) formed on the first transparent electrode, formed from materials including hydrogenated amorphous silicon carbide (a-Si:C:H). A read-out light-blocking layer (4) is formed on top of the photosensor layer (3) and is formed from amorphous hydrogenated carbon (a-C:H). The high reflectance dielectric multilayer mirror (5) is formed on top of the light-blocking layer (4) and can be made of alternating the a-Si:C:H layers with a higher refractive index and the a-C:H layers with lower reflective index. The modulator also has a second transparent substrate (1a), a second transparent electrode (2a) formed on the second transparent substrate (1a), and a liquid crystal layer (8) disposed between the dielectric mirror (5) and the second transparent electrode (2a). The invention allows more efficient separation of the input and read lights and increases the read light reflection, resulting in improvements to the input sensitivity, resolution, contrast ratio, and diffraction efficacy.

Abstract: A display having polymer dispersed liquid crystals, which display comprises a transparent substrate; a layer comprising polymer-dispersed cholesteric liquid crystal disposed over the substrate, which layer has more than one stable optical state in the absence of an electrical field. The display further comprises a first transparent conductor disposed between the state changing layer and the transparent support, a second conductor on the other side of the state changing layer so that when a field is applied between the first and second conductors, the liquid crystals change state. It has been found advantageous to have a non-conductive, non-field spreading dark layer of sub-micron pigments in a binder for providing an improved light absorbing function, which dark layer is disposed between the layer of polymer-dispersed cholesteric liquid crystal and the second conductor.
