摘要: A driving apparatus of a liquid crystal display device includes a liquid crystal display panel display a video signal by use of a liquid crystal cell of a matrix shape. A plurality of data drive circuits generate a polarity pattern of the video signal in accordance with a polarity signal and supply the polarity pattern to the liquid crystal cell through a plurality of output channels. A polarity controller controls the polarity signal and supplies the polarity signal to the data drive circuits on the basis of a first selection signal corresponding to the number of the output channels of one drive circuit and a second selection signal corresponding to a repetition period of the polarity pattern.
