    摘要: The liquid crystal cell (30) for the optical change-over switch comprises a pair of transparent substrates (1), a pair of transparent flat electrodes (2) provided on the respective opposing surfaces of the substrates, orientation control films (3) provided on the flat electrodes (2), two pair of comb shaped electrodes (33) respectively provided on the orientation control films (3), and a ferroelectric liquid crystal layer (4) confined between the substrates (1). The optical incidence plane (31) to the cell (30) is so selected that the plane (31) is away from the helical axes (9) of the ferroelectric liquid crystal in the cell (30) in the order of somewhat greater than the tilt angle (.theta..sub.t) of the ferroelectric liquid crystal. The pair of flat electrodes (2) generate a first electric field (37a) perpendicular to the layer (32) and orient the long axes of the ferroelectric liquid crystal molecules into a first orientation (35a') parallel to the layer (32 ) to induce a first refractive index which causes simultaneous reflection of unpolarized light beam (7+8) with a predetermined incidence angle (.theta.). The two pair of comb shaped electrodes (33) generate a second electric field (37b') parallel to the layer and perpendicular to the helical axes (9) and orient the long axes of the molecules into a second orientation (35b') not in parallel to the layer (32) to induce a second refractive index which causes simultaneous transmission of the unpolarized light beam (7+8) with the predetermined incidence angle (.theta.).

    摘要: A liquid crystal optical modulation element is disclosed. The modulation element comprises two transparent substrates positioned so as to face each other; a transparent electrode provided on the facing surface of the transparent substrates; a transparent insulating/orientation control layer provided on each of the facing surfaces of the transparent electrodes, having insulating properties and orientating the liquid crystal molecules in the proximity thereof in a preferential direction substantially parallel to the surfaces of the substrates; a liquid crystal layer exhibiting ferroelectricity, sandwiched between the insulating/orientation control layers; and means for polarizing light passing through said liquid crystal layer.The liquid crystal optical modulation element of the present invention is produced by the steps of coating transparent electrodes onto transparent sbstrates; coating polyimide films so as to cover the transparent electrodes; rubbing the polyimide coating films; positioning the transparent substrates parallel to each other so that the rubbed polyimide coating films face each other so that a liquid crystal cell is thereby assembled; introducing a liquid crystal exhibiting ferroelectricity into the cell thus formed and sealing the cell; and providing polarizers on the external surfaces of the substrates.

    摘要: A voltage of an intensity corresponding to information to be recorded is applied to a recording medium which comprises a film containing a charge generating material. The film is sandwiched between two electrodes. Electric charges are accumulated in the recording medium upon application of the voltage so that information is recorded. When light is irradiated to the recording medium, the stored charges are converted into photo-current. The recorded information is read out by detecting the photo-current. When the electrodes are short-circuited, the recorded information is erased.
