1. A liquid crystal display apparatus having a pair of substrates of which at least one substrate is transparent and a liquid crystal layer sandwiched between the substrates, comprising:

  • a plurality of first scanning electrodes formed on one of the substrates;

    a plurality of signal electrodes intersecting in a matrix form with said plurality of first scanning electrodes;

    a plurality of second scanning electrodes provided along said first scanning electrodes or said signal electrodes;

    wherein the display apparatus further comprises, within each of the regions surrounded by said plurality of first scanning electrodes and said plurality of signal electrodes;

    (a) a data holding circuit connected to a corresponding first scanning electrode, signal electrode, and second scanning electrode for fetching and storing display data from the signal electrode in response to voltages applied to the first and the second scanning electrodes;

    (b) a capacitor connected to said data holding circuit;

    (c) a switching device connected to said capacitor and having a switching operation thereof controlled by a voltage of the capacitor; and

    (d) a display electrode connected to said switching device;

    wherein a drive voltage of the liquid crystal display apparatus is an alternating current voltage having a period which is shorter than a period of fetching by the display data holding circuit.
