A display device includes a display panel, a plurality of switch circuits and a charge sharing controller. The display panel includes a plurality of pixels which are connected to a plurality of gate lines and a plurality of source lines. The plurality of source lines are divided into a plurality of source line groups. The plurality of switch circuit electrically connect source lines included in each of the plurality of source line groups based on each of a plurality of group switch control signals to perform charge sharing. The charge sharing controller generates each of the plurality of group switch control signals based on first most significant bits (MSBs) of each of a plurality of (K−1)th digital data groups and second MSBs of each of a plurality of Kth digital data group.
