    Abstract: A bright, and contrasty reflective display can be performed without using polarizer films, and display switching can be performed fast. A ferroelectric liquid crystal is sandwiched between substrates, and electrodes are formed face to face with each other in a direction parallel to the substrates. The ferroelectric liquid crystal, when no electric field is applied to it, goes into a planer state in which a helical axis becomes perpendicular to or almost perpendicular to the substrates, selectively reflecting light of specific wavelengths in a visible region. A driving circuit applies an electric field between the electrodes in a direction perpendicular to or almost perpendicular to the helical axis of the ferroelectric liquid crystal in the planer state. When an electric field equal to or greater than a threshold value is applied, the ferroelectric liquid crystal changes from a planer state due to a low electric field to a homeotropic state in which a helical structure disappears, going into a transparent state, wherein, in the homeotropic state, a cyclic change of refractive index disappears and liquid crystal molecules are arranged in the direction of the electric field. The change in this case is performed fast because the ferroelectric liquid crystal has spontaneous polarization. The ferroelectric liquid crystal may be filled between a pair of transparent substrates each having a transparent electrode formed thereon to apply electric fields in a direction parallel to or almost parallel to the helical axes.

    Abstract: In a light control element whose reflection factor or transmission factor varies in response to an external stimulus such as voltage by having layer structure in which the refractive index varies periodically, design is made such that the difference in refractive index between adjacent layers in a reflected state becomes sufficiently great and the half-amplitude level of reflection spectrum becomes sufficiently high. A light control layer is interposed between supporting plates, and the light control layer is obtained by alternately laminating a nonsensitive layer and a sensitive layer in the Z-axis direction.In the nonsensitive layer, the oriented direction of the liquid crystal is fixed in the X-axis direction, while in the sensitive layer, the liquid crystal is oriented in the X-axis direction. On the supporting plate, a pair of electrodes and facing to each other in the Y-direction are so formed as to extend in a striped shape in the X-axis direction respectively. When voltage is applied between electrodes, the oriented direction of the liquid crystal in the sensitive layer changes into the Y-axis direction.

The ends of the divided electrodes may overlap with each other, with an insulating layer being layered therebetween. In this case, no gap is present between the adjacent divided electrodes. A distance t between the display panel and the document table is preferably 3 mm.ltoreq.t.ltoreq.30 mm.
