The present specification discloses a drive circuit of a liquid crystal display device that transfers image data to a liquid crystal panel which is able to reduce the amount of change of the value of each bit of data that may be transferred over a bus line. In the case the number of data signals that cause a polarity change in the output to a bus line is equal to or greater than the majority of data signals for each of four output ports, a controller inverts the polarity of the data signals, and outputs data from each output port to the bus line. In addition, the controller outputs polarity inversion signals, which indicate that the polarity of data signals output to the bus line has been inverted, for each output port.
