    摘要： A liquid crystal display device is constituted by a pair of electrode plates each having a plurality of elongated electrodes, and a layer of ferroelectric liquid crystal disposed between the electrode plates so as to form a pixel at each intersection of elongated electrodes disposed respectively on the pair of electrodes plates. At least one electrode plate is provided with an unevenness at each pixel so as to form a cell thickness gradient (α₁α₂), within each pixel, and at least one electrode plate is provided with at least three types of color filters each corresponding to a pixel. Further, each color filter and/or each pixel (R,G,B) is set to have an area and/or a shape varying depending on a local cell thickness so that light quantities or sensible light quantities transmitted through the respective filters and the liquid crystal layer are identical to each other regardless of the type of color filter. A similar pixel pattern deformation is effective for providing a linear T (transmittance) - log V (voltage) characteristic. Color pixels pattern deformation may preferably be effected in a complementary manner with respect to different colors.

    摘要： A liquid crystal device is formed by a plurality of scanning electrodes, a plurality of data electrodes intersecting the scanning electrodes, and a bistable liquid crystal showing a first stable orientation state and a second stable orientation state disposed between the scanning electrodes and the data electrodes so as to form a pixel at each intersection of the scanning electrodes and the data electrodes. The liquid crystal device is driven according to a scheme wherein a pixel is written in a first orientation state (or at a gradation level k) in two steps including: a first step of applying a prescribed voltage for causing the second orientation state to the pixel and then applying a voltage of at least V 1 (or a voltage Va) to the pixel, and a second step of applying a voltage of at least V 2 (or a voltage Vb) to the pixel, wherein V 1 (Va) denotes a threshold voltage required for converting a pixel in the second orientation state into the first orientation state (into the gradation level k) after applying the prescribed voltage for causing the second orientation state to the pixel in the first orientation state, and V 2 (Vb) denotes a threshold voltage required for converting a pixel in the second orientation state into the first orientation state (into the gradation level k) after applying the prescribed voltage for causing the second orientation state to the pixel in the second orientation state.
