A liquid crystal display device comprises a substrate, two electrode-attached substrates formed by sequentially superposing electrode layers and orientation layers on the substrate and disposed so as to oppose the orientation layers to each other across a gap, and a liquid crystal composition placed in the gap and consequently interposed between the two electrode-attached substrates, which liquid crystal display device is characterized in that the orientation layers is furnished with multiply divided liquid crystal orientation areas and the orientation areas severally have directions of orientation set either in a radial pattern or in the shape of concentric rings.

A liquid crystal display element comprises a pair of substrates having electrodes formed thereon, and a liquid crystal layer interposed between the substrates. The liquid crystal layer contains a gel of a mixture comprising an organic compound having a perfluoroalkyl group and a liquid crystal material.

Disclosed herein is a liquid-crystal orientating film which is a polymer film consisting of stripe-shaped contracted portions extending in a predetermined direction and non-contracted portions located adjacent to the contracted portions, and which is designed to orientate liquid-crystal molecules in the direction in which the portions of the film are contracted and non-contracted. The liquid-crystal orientating film has been manufactured by applying light to selected portions of a polymer film, thereby photo-curing these portions, thus forming stripe-shaped contracted portions, stretching the remaining portions of the film, which are located adjacent to the contracted portions, by virtue of the contraction of the portions applied with light.

Disclosed is an electrochromic display element having an electrochromic material layer and an ion-conductive material layer being in contact therewith, characterized in that said electrochromic layer comprises a transition metal oxide and said ion-conductive material layer comprises a light-transmissive organic polymeric resin and an inorganic ion-conductive material.

Electrochromic display element

A solid-state optical device with a plurality of cells having a plurality of optical functions is disclosed. Each of the cells comprises a transparent substrate, an anti-reflection film formed on the lower surface of the transparent substrate, a MOS transistor and a capacitor formed on the upper surface of the transparent substrate, a liquid crystal display device formed on the MOS transistor and capacitor, and window for leading a light signal incident on the liquid crystal display device from above to the transparent substrate. At least either a channel region of the MOS transistor and a region intervening between pair electrodes of the capacitor is formed of a photoconductive film. A transparent medium intervenes between the transparent substrate and photoconductive film such that light signal led through the window to the transparent substrate is reflected by an object disposed in contact with anti-reflection film to reach the photoconductive film, thereby generating carriers therein.
