摘要： 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.
摘要翻译：可以在不使用偏振片的情况下执行明亮且对比的反射显示，并且可以快速执行显示切换。铁电液晶夹在基板之间，并且电极在平行于基板的方向上彼此面对。当不施加电场时，铁电液晶进入平面状态，其中螺旋轴垂直于或几乎垂直于基板，选择性地反射可见光区域中特定波长的光。驱动电路在平面状态下沿与铁电液晶的螺旋轴垂直或几乎垂直的方向在电极之间施加电场。当施加等于或大于阈值的电场时，铁电液晶由于低电场而从平面状态变为螺旋结构消失的垂面状态，进入透明状态，其中，在垂直状态，折射率的循环变化消失，液晶分子沿电场方向排列。这种情况的变化是快速进行的，因为铁电液晶具有自发极化。铁电液晶可以填充在其上形成有透明电极的一对透明基板之间，以沿与螺旋轴平行或几乎平行的方向施加电场。

摘要： 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.

摘要： A cholesteric liquid crystal display capable of rewriting at a high speed is provided, which includes a cholesteric liquid crystal display element forming pixels at intersection portions of scan-electrodes of a scan-electrode group and data-electrodes of a data-electrode group, in which L-lines (L: integer lager than 2) of the scan-electrodes each of the scan-electrode group form a block. The drive circuit sequentially selects one block during one selection time, simultaneously applies coded drive voltages each corresponding to the L-lines of the scan-electrodes in the selected block, and applies coded data-voltages each corresponding to data-electrodes of the data-electrode group synchronously with the drive voltages.
