1. A display device comprising:
a display panel including multiple pixels, each of the multiple pixels including multiple sub-pixels;
multiple data lines respectively connected to the multiple sub-pixels;
multiple gate lines respectively connected to the multiple pixels; and
N multiplexers (MUX) disposed at input terminals of the multiple data lines, where N is a natural number larger than 1,
wherein, in one horizontal (H) period, a length of a turn-on period of a first MUX is different from a length of a turn-on period of an Nth MUX, where the one H period is a period in which a scan signal is supplied through one gate line among the multiple gate lines,
wherein, in the one H period, a MUX having the longest turn-on period is performed last comparing to the other MUXs, and the turn-on period of the MUX that is performed last overlaps a sampling period of a scan signal, and
wherein, a length of the turn-on period of the MUX that is performed last is larger than a length of the sampling period of the scan signal.
