1. A method of driving a matrix type liquid crystal display device including a liquid crystal picture forming element at the intersection of each line electrode and column electrode and where each liquid crystal element is provided with a thin film transistor connected to the row electrode and the column electrode, comprising the steps of:

  • (a) applying a scanning signal pulse to the line electrode; and

    (b) applying a data signal pulse to the column electrode where the scanning signal pulse is advanced in time with respect to the data signal pulse, the advancement in time of the scanning signal pulse being determined in accordance with a resistor-capacitor time constant associated with a capacitance formed by the liquid crystal element and the line electrode and a resistance of the line electrode.
