A frequency converting section (101), which is included in a liquid crystal display apparatus, generates an output video signal by inserting one non-image signal, which is to be concurrently written into pixels on L (L is an integer equal to or greater than two) gate lines of the liquid crystal panel, for one line, between image signals composing an input video signal, for corresponding L lines, and adjusting a number of horizontal scanning periods of the output video signal in a vertical blanking period so that a number of horizontal scanning periods composing one frame period is (L+1)x(2N+1) (N is an integer). Thus, when anti-back-transition driving is performed using a liquid crystal panel in OCB mode, it is possible to minimize increase in a driving frequency, prevent irregularity of brightness caused by AC driving of the liquid crystal panel, and reduce a cost. <IMAGE> |
