Abstract
A method of driving the liquid crystal display device includes the steps of preparing a first drive voltage circuit formed by plural first output circuits having a latch circuit for latching display data and being connected to the latch circuit and outputting LC driving voltages of positive polarity and second output circuits having a latch circuit for latching display data and being connected to the latch circuit and outputting LC driving voltages of negative polarity arranged alternately, and a second drive voltage circuit formed by plural first output circuits having a latch circuit for latching display data and being connected to the latch circuit and outputting LC driving voltages of positive polarity and second output circuits having a latch circuit for latching display data and being connected to the latch circuit and outputting LC driving voltages of negative polarity arranged alternately in opposite polarity.
