ABSTRACT:
In a method of driving a liquid crystal matrix panel, a group of voltage pulses are applied to each pixel connected to a scanning line during a reset period prior to a selection period so as to reset the state of each pixel before writing data. When the voltage pulse group contains a voltage pulse having a voltage whose absolute value is at least equal an absolute value of a threshold voltage of the liquid crystal, the group also contains, before or after the voltage pulse, a voltage pulse having a voltage whose absolute value is smaller than the absolute value of the threshold voltage and whose polarity is opposite to that of the former voltage pulse.
