1. A liquid crystal device comprising:

  • a pair of substrates;

    a scanning driver provided over one of said substrates;

    a data driver provided over said one of said substrates;

    a liquid crystal provided between said substrates;

    a plurality of pixels arranged in said liquid crystal device and having a plurality of pairs of first and second electrodes respectively for applying voltages between said first and second electrodes of said plurality of pairs, said first and second electrodes being provided over said one of said substrates to effect the application of said voltages to said liquid crystal of said pixels in an in-plane switching mode, wherein said liquid crystal of said pixels responds to said voltages in a field inversion, and wherein the application of each of said voltages is carried out by applying an image write signal to one of said first and second electrodes of corresponding one of said pairs and setting the other of said first and second electrodes of said corresponding one of said pairs to a reference potential, and wherein a potential level of said image write signal is always of a single polarity.
