Abstract:
A liquid crystal display apparatus having a driving circuit comprising:an anti-ferroelectric liquid crystal sandwiched between an active matrix substrate and an opposed substrate, the active matrix substrate having a plurality of signal lines and a plurality of scanning lines arrayed in a matrix fashion to constitute a plurality of pixels; signal line driving means driving the plurality of signal lines; scanning line driving means for driving the plurality of scanning lines; reset voltage applying means for applying a reset voltage to the scanning lines such that: prior to video signals being written to all pixels on any one of the plurality of scanning lines in one horizontal period and over a plurality of horizontal periods continuous to the one horizontal period, the reset voltage applying means applies the reset voltage to the same number of scanning lines adjacent to the one scanning line as that of the plurality of horizontal periods continuous to the one horizontal period, the reset voltage being applied to the adjacent scanning lines to be written subsequent to the one horizontal period and in a blanking period present in each of the plurality of horizontal periods; and reset voltage applying means for the signal lines for outputting data of â€œ0â€  to all the signal lines for each of the blanking periods.
