A display apparatus including an image signal controller, a dither memory, and a display panel. The display panel includes a dither block including pixels displaying an image in response to a dither image signal. The dither memory stores a dither set corresponding to a dither level. The dither set includes dither patterns. Each dither pattern determines that a corresponding pixel is a dither pixel that is to be dithered and a polarity of the dither pixel. A combined matrix, obtained by adding respective dither polarity matrices of the dither patterns, is zero. Thus, although the same image is displayed for a long time, an after-image caused by accumulation of the polarity may be prevented.
