Abstract: A display apparatus includes a display panel including a plurality of horizontal lines each including a plurality of pixels, a timing controller configured to output a polarity control signal representing a polarity corresponding to each of the plurality of horizontal lines and having a value inverted by n horizontal line units, and a source driver configured to generate a timing pulse signal sequentially representing a data charging time of each of the plurality of horizontal lines and to output a data voltage, having a polarity corresponding to each of the plurality of horizontal lines, to the display panel on the basis of the timing pulse signal. When a value of the polarity control signal is inverted, the source driver generates the timing pulse signal including a data charging time corresponding to a count value obtained by counting a number of horizontal lines after a polarity is inverted.
