Abstract: A display apparatus includes a liquid crystal panel; and a source driver configured to output an image signal to the liquid crystal panel. The source driver may include a digital-to-analog converter (DA converter) configured to convert digital image data into an image signal of normal polarity and an image signal of inversion polarity; a plurality of multiplexers each of which receives the image signal of the normal polarity and the image signal of the inversion polarity from the DA converter, and outputs the image signal of the normal polarity and the image signal of the inversion polarity as they are or cross outputs the image signal of the normal polarity and the image signal of the inversion polarity; and an inversion controller configured to output a control signal to each of the plurality of multiplexers through a plurality of output terminals respectively connected to the plurality of multiplexers. Each of the plurality of multiplexers may be configured to output the image signal of the normal polarity and the image signal of the inversion polarity as they are in response to a first control signal of the inversion controller, and to cross output the image signal of the normal polarity and the image signal of the inversion polarity in response to a second control signal of the inversion controller.
