Abstract
A liquid crystal display apparatus includes synchronization signal extracting means for extracting a vertical synchronization signal from a noninterlace signal, first reversal signal generating means for generating a first polarity reversal signal that causes reversal of polarity of a signal voltage every frame for a switching device associated with each of pixels according to the vertical synchronization signal, reversal control signal generating means for generating a reversal control signal according to a result of comparison between frames of the noninterlace signal, second reversal signal generating means for generating a second polarity reversal signal by reversing polarity of the first polarity reversal signal according to the reversal control signal, and switching device driving means for driving each of switching devices according to the second polarity reversal signal.
