A display device can include a display panel including multiple pixels each of which includes multiple sub-pixels. The display device can further include multiple data lines respectively connected to the multiple sub-pixels, multiple gate lines respectively connected to the multiple pixels, and N multiplexers (MUX) (N is a natural number larger than 1) disposed at input terminals of the multiple data lines. In one horizontal (H) period, a length of a turn-on period of a first MUX can be different from that 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.
