Abstract:
A liquid crystal display apparatus, comprising:a display panel including scanning electrodes and data electrodes intersecting the scanning electrodes so as to form a matrix of pixels each comprising two sub-pixels formed at intersections of an adjacent two of the scanning electrodes and one of the data electrodes;a ferroelectric liquid crystal disposed between the scanning electrodes and the data electrodes and capable of assuming an antiferroelectric first stable state under application of no voltage, and a ferroelectric second stable state and a ferroelectric third stable state under application of voltages corresponding to polarities of the applied voltages;polarizing means for visually displaying the first stable state of the liquid crystal as a dark state, and the second and third stable states of the liquid crystal as bright states; anddrive means for applying voltages to the scanning electrodes and the data electrodes so that, for each pixel displayed in a bright state in each frame, the liquid crystal is placed in the second and third stable states at one and the other of the two sub-pixels on the adjacent two scanning electrodes receiving voltages of mutually opposite polarities.
