Abstract:
A method of driving a liquid crystal display device that comprises a plurality of first electrodes to which a scanning signal is applied, a plurality of second electrodes to which a data signal is applied, and a plurality of pixels formed by intersecting said first and second electrodes, each of said pixels comprising a liquid crystal layer and a two-terminal element having non-linear resistance characteristics connected in series therewith, said method comprising the steps of:(a) applying a write voltage to each of said pixels based on a difference signal between said scanning signal and said data signal during a data write period TB in which each of said first electrodes is selected and said liquid crystal layer of each of said pixels is charged with a data charge voltage corresponding to said data signal;(b) applying a hold voltage of an absolute value smaller than said write voltage to each of said pixels based on said difference signal during a data hold period after said data write period and(c) applying a compensatory voltage to each of said pixels during a compensatory period TA based on said difference signal before said data write period a compensatory charge voltage applied to the liquid crystal layer has a polarity opposite to a polarity of said data charge voltage and is charged into said liquid crystal layer of each of said pixels, said compensatory charge voltage being set to have a relationship with said data charge voltage such that an absolute value of said compensatory charge voltage is small if said data charge voltage is large, but large if said data charge voltage is small.
