摘要： A liquid crystal display device which comprises an orientation film and at least one charge transporting material doped in the orientation film. The charge transporting material having an amount being sufficient to cause a leakage of an electric charge temporarily accumulated in the orientation film or a portion adjacent thereto, during an operation of the device, to thereby inhibit a formation of an electric bilayer in the device. Since the formation of an electric bilayer is inhibited, generation of crosstalk and reduction of display characteristics such as memory properties of the LC display device are effectively prevented.

摘要： A liquid crystal display device comprising a layer of a ferroelectric liquid crystal material sandwiched between opposed first and second electrodes. The display device further comprises a dielectric layer as a capacitative element which is electrically connected through an electrically conductive connecting means to the first electrode so that the dielectric layer and the liquid crystal material are connected in parallel with regard to an external electric source. The display device provides a large area and high information content display, high contrast ratio display, and high gradation display, together with a stabilized memory effect.

摘要： A ferroelectric liquid crystal is formed by incorporating, as the main component, a predetermined amount of a ferroelectric liquid crystal having a specific naphthalene ring structure into conventional liquid crystals. This liquid crystal composition has a broad driving temperature range and in particular, can be effectively driven even in a low-temperature region. Moreover, this liquid crystal composition has a high orientation uniformity, a high memory stability, and a high contrast ratio.

摘要： A bright and large information capacity projection-type multi-color liquid crystal display is realized by a display device which includes a liquid crystal panel having a plurality of layers of cholesteric-nematic phase transition type liquid crystals having a positive dielectric anisotropy and phase transition hysterisis when a voltage is applied. The liquid crystals are driven to be in homeotropic and focalconic textures which are maintained when at a certain voltage is applied thereto. A desired color of the projected display can be obtained by selecting a thickness of the liquid crystal layer and a refractive index anisotropy of the liquid crystal of the liquid crystal layers.
