Abstract:
A liquid crystal display device comprising:a pair of substrates opposing each other, each having an electrode and an aligning film on its opposing surface, said aligning film having been rubbed in a predetermined direction;a layer of bistable nematic liquid crystal sealed in a space between said substrate, the molecules of said liquid crystal assuming a first metastable aligned state when a reset pulse voltage high enough to align the molecules almost vertically to the substrates and then a first state-selecting pulse voltage lower than the reset pulse voltage are applied between the opposing electrodes, or assuming a second metastable aligned state when the reset pulse voltage and then a second state-selecting pulse voltage lower than the reset pulse voltage are applied between the opposing electrodes, being tilted at an angle to said substrates in accordance with an effective value of the voltage applied between the opposing electrodes while remaining in the first and second metastable aligned states; andat least one polarizing plate arranged on the outside of at least one of said substrates.
