Abstract
Provided is a display driving circuit eliminating occurrence of lateral stripes in the first frame from which display corresponding to a video signal is started in CC driving premised on line inversion driving. A source bus line drive circuit outputs a source signal whose polarity is reversed in sync with horizontal scanning period for each row and whose polarity is opposite in an adjacent horizontal scanning period on the same row. A CS bus line drive circuit outputs, after the horizontal scanning period for each row, a CS signal with potential switched along a direction according to polarity of the source signal in the horizontal scanning period concerned. The CS bus line drive circuit outputs the CS signal in a first frame so that potential of the CS signal when the switching element on one row is switched is different from potential of a CS signal on an adjacent row.
