摘要： A liquid crystal display device comprises a pair of substrates opposing each other, each having an electrode and an aligning film on an inner surface, a layer of bistable nematic liquid crystal sealed in a space between substrate, and two polarizing plates. A reset pulse voltage high enough to align the molecules almost vertically to the substrates is applied to the layer of liquid crystal. Then, a first state-selecting pulse voltage lower than the reset pulse voltage is applied between the electrodes, whereby the molecules of the liquid crystal assume a first metastable aligned state. Alternatively, a second state-selecting pulse voltage lower than the reset pulse voltage is applied between the electrodes, whereby the molecules of the liquid crystal assume a second metastable aligned state. The liquid crystal molecules are tilted at an angle to the substrates in accordance with the effective value of the first state-selecting pulse voltage while remaining in the first metastable aligned state, and are tilted at a different angle to the substrates in accordance with the effective value of the second state-selecting pulse voltage while remaining in the second metastable aligned state.

摘要： A liquid crystal layer is sealed between a pair of substrates on which opposite electrodes are formed. The liquid crystal layer is formed of a liquid crystal which exhibits an antiferroelectric phase while the liquid crystal is in a bulk state. When the liquid crystal is sealed between the substrates as the liquid crystal layer, the liquid crystal exhibits a ferrielectric phase wherein liquid crystal molecules aligned in a first state of being aligned in a first direction and liquid crystal molecules aligned in a second state of being aligned in a second direction are present in predetermined order. In accordance with the polarity and magnitude of a voltage applied between the opposite electrodes, the ratio of the number of liquid crystal molecules aligned in the first state to the number of liquid crystal molecules aligned in the second state varies such that the direction of the director of the liquid crystal layer varies continuously. Gradation display can be achieved by detecting a variation in the director through the use of a pair of polarization plates arranged in a crossed Nicols fashion.

An aligning film covers the pixel and counter electrodes. A liquid crystal layer is sandwiched between the front and rear substrates and has an initial aligned state in which liquid crystal molecules are aligned in a predetermined direction by the aligning films. A polarizing member is arranged on an outer side of the front substrate such that a polarization axis of the polarizing member crosses an aligning direction of liquid crystal molecules adjacent to the aligning film on the front substrate side at an angle other than a right angle. A reflecting member is arranged on the rear substrate side.
