A liquid crystal display device having a matrix of pixels in driven for gradational display with better temperature compensation and better flicker suppression by a driving method, wherein (a) a first voltage signal is applied to a pixel on a selected scanning line, the first voltage signal including a clear pulse, a writing pulse of a polarity opposite to that of the clear pulse and a correction pulse of a polarity opposite to that of the writing pulse, (b) a second voltage signal is applied to an associated pixel on a subsequent scanning line, the second voltage signal including a clear pulse, a writing pulse and a correction pulse of which polarities are respectively opposite to corresponding pulses of the first voltage signal, and (c) the correction pulse applied to the pixel on the selected scanning line is determined based on gradation data for the associated pixel on the subsequent scanning line, and the writing pulse applied to the pixel on the selected scanning line is determined based on gradation data for the pixel on the selected scanning line and the above-determined correction pulse.
A liquid crystal apparatus, comprising a liquid crystal device of the type comprising a pair of oppositely disposed electrode plates having thereon a group of scanning electrodes and a group of data electrodes, respectively, and a ferroelectric liquid crystal layer disposed between the pair of electrode plates so as to form a pixel at each intersection of the scanning electrodes and data electrodes;
